History FandomRivalry / RealLife

* Theists vs. atheists. Religious vs. non-religious. Gnostics vs. agnostics.
** This also applies to the countless interreligious and intra-religion feuds.

** Speaking of ''T.Rex’’ the predator vs scavenger debate has been going on for decades. Then there’s the [[TakeAThirdOption view that it did both depending on what was available and catchable at the moment]]

* In the dinosaur fanboy community, one of the biggest debates involves who would win in a fight between ''[[KingOfTheDinosaurs Tyrannosaurus]]'' and ''[[AlwaysABiggerFish Spinosaurus]]'' (two of the largest carnivorous dinosaurs), with both sides involving fanboys who constantly think of reasons that their theropod is bigger or stronger while bashing the other. The feud probably started because the ''Spinosaurus'' replaced the ''T. rex'' in ''Film/JurassicParkIII''. Things get worse when the Carcharodontosaurus ''[[TakeAThirdOption Giganotosaurus]]'' gets involved, with fanboys practically doing the same thing as the other two carnivores. In fact, it would probably extend to a battle of ''any'' of the largest carnivorous dinosaurs.

* [[ArtisticLicensePaleontology Hardcore palaeontology enthusiasts]] vs. people who like [[RaptorAttack featherless dromaeosaurs]] (and other dinosaurs which are thought to have been feathered).

** In UsefulNotes/{{Philadelphia}}, there's the cheesesteak, with the most well-known being Pat's Steaks vs. Geno's Steaks. Most actual Philadelphians actually eschew both, leaving them for the tourists, but still argue over which of the various alternatives they prefer. Common ones include Jim's Steaks, Tony Luke's, and John's Roast Pork--which is more famous for its cheesesteaks. Some in nearby South Jersey might also throw in Donkey's Place in Camden,[[note]]Creator/AnthonyBourdain called Donkey's steak possibly the best he'd ever had, which you can't ignore even accounting for the Bergen County-raised chef's Jersey pride[[/note]] but although everyone agrees the steaks are good, it usually doesn't get mentioned because (1) Camden is um, [[{{Gangsterland}} Camden]] and (2) the steaks are ''weird'' (served on a kaiser roll--literally no other place does that--and only with white American cheese--which other places have as an ''option'' but don't insist on).

* Norwegian fashion models Juliane Snekkestad and Synnøve Ardal have a heavy rivalry, with both fandoms disliking the other one. Juliane fans often think Synnøve is too much [[TheGenericGuy too ordinary and generic-looking blonde girl]], while Synnøve Ardal fans tend to see the Juliane Snekkestad fandom as AlphaBitch-types who mock them for liking someone who is a more conventional GirlyGirl supermodel, especially in light of Juliane saying "I am a boy in a female model's body" which implies she is either a {{Tomboy}} or less likely, [[{{Transgender}} [[UsefulNotes/{{Transgender}} a trans man]].. [[GermansLoveDavidHasselhoff This applies in the United Kingdom where they are more popular than their home country of Norway]].

* iPhone vs. Android. iPhone users are stereotyped by Android users as being pretentious rich folks who only buy iPhones because of the Apple brand, while Android users are dissed by iPhone users are being too poor to get "good" phones. The arguments over preferred phones is often very reminiscent of UsefulNotes/ConsoleWars.

** Serious oil painters have a big bone to pick with fans of Bob Ross and Bill Alexander who are both known for their roles in making oil painting easily accessible to amateurs via their PBS TV shows such as ''The Magic Of Oil Painting''. Some serious painters feel that Ross and Alexander were not teaching true painting techniques but just a handful of hacks, but others feel that ''anything'' that gets people into painting is a good thing and there's plenty of time to learn more advanced painting techniques as you gain experience.

* Boeing vs. Airbus. This one's ''real'' SeriousBusiness--after all, the former's biggest fanboy is a certain scholarly gent who goes by the name of Uncle Sam, while the latter has a major fangirl in Europa (no, not the moon of Jupiter). Boeing fans claim Airbus is an upstart company with a crummy name, that gets an unfair leg up with preferential loans from the EU. Airbus reply that Boeing is NotSoDifferent, and is only kept afloat by Pentagon pork and US diplomatic pressure on countries to make their flag carriers buy it. Of course, this mirrors the fact that the companies themselves ''utterly loathe each other'', to the extent that Boeing ignored [[CassandraTruth Airbus's warnings over the 787 battery fiasco]], believing them to be a sneaky plot. This rivalry ranges from mutual bitter WTO disputes, to hilariously bitchy [[http://www.bloomberg.com/news/2012-11-26/airbus-ads-jab-boeing-on-new-jets-as-planemaker-rivalry-sharpens.html advertisement]] [[https://www.youtube.com/watch?v=9TbRyhLJqT0 wars]].

** Yaoi fans: There are the ones who like the effeminate boys, and the ones that like [[{{Bara}} muscular guys]].

** And of course RuleThirtyFour vs. fans who don't want to see their favorite shows as sexual.

* Theists vs. atheists. Someone was going to say it.
** And (to a certain extent) [[TakeAThirdOption agnostics]].
** This also applies to the countless interreligion and intra-religion feuds.

*** The real rivalry there is Dr Pepper vs Mr. Pibb.

* Domino's vs. Pizza Hut.

** In America, the rivalry may exist more due to problems of in-group/out-group identification than actual differences, making this a sad case of manufactured rivalry.[[note]] There are two views of party composition: either bipolar (two huge blocs at each side of the spectrum and a small number of independents/undecideds/apathetics) or unipolar (traditional bell-curve: the majority of people fall somewhere in the middle, and as you move toward the extremes of either side, numbers drop off). Each view favors different strategies -- if you believe the bipolar model, you antagonize your base by driving them to the polls for state issues (this was Karl Rove's strategy in 2004, when many states voted on gay marriage); if you believe the unipolar model, you build a platform around appealing to as many people as possible and avoid extreme stances. The problem (and rivalry) can be partly explained by the fact that the most extreme voices are often the loudest and election math: not every district is hospitable to moderation, nor is every state. What helps a candidate win a Senate seat in California may backfire spectacularly in Ohio. House races are even worse due to gerrymandering. State races are also tricky, as "conservative" and "liberal" vary by location, and sometimes state officers (particularly governors) are put in a position where throwing the national candidate from their party under the bus is the better move. This is one reason candidates have an incentive to favor rhetoric over actual policy proposals. Third party candidates often criticize Democrat-Republican races as a choice between the same thing in different packaging.[[/note]]
* [[RailEnthusiast Railfans]] tend to strongly dislike bus fans and bus transportation in general due to the mostly correct perception that buses killed the majority of streetcar, commuter and long distance rail passenger services across North America. Most railfans will choose to walk long distances to avoid having to ride a bus.

** For handguns, the pre-eminent rivalry is undoubtedly 1911 vs. Glock. They could not be more opposite: the 1911 is a single-stack, heavy, all-steel, single action only hammer-fired gun with multiple external safety features (with both a thumb and a grip safety), while Glocks are double-stack [[labelnote:note]]Single-stack Glocks didn't exist until the Glock 36 was released in 2000, and it took another 14 years before Glock came out with another single-stack model with the [=G42=][[/labelnote]], polymer-framed, lightweight, striker-fired guns with no external safeties (it has a trigger safety, which means it only fires if the trigger is pulled all the way back). And these two models also serve as stand-ins for the larger debate between polymer vs. metal framed pistols: Despite the fact that polymer guns have taken over the firearms market for civilians, law enforcement, and military, there are still lots of people who will swear by steel only and have no time for "plastic" guns, while those on the other side look at the 1911 and its contemporaries as obsolete relics from a by-gone era.

** To a lesser extent, shotgun fans are divided between Mossberg and Remington, especially for pump-action, and there is further debate between whole pump vs semi-auto shotguns for home defense and competition shooters. For hunters and clay shooters, this is also further extended between double-barrel break action-shotguns: side-by-sides or over/unders?

* As mentioned in the Sports section below, St. Louis and Chicago already have a baseball rivalry but this extends to the two cities themselves since they are basically the two major cities fighting over [[FlyoverCountry the center of the country]]... Kansas City being a possible third option.

* In the dinosaur fanboy community, one of the biggest debates involves who would win in a fight between ''[[KingOfTheDinosaurs Tyrannosaurus]]'' and ''[[AlwaysABiggerFish Spinosaurus]]'' (two of the largest carnivorous dinosaurs), with both sides involving fanboys who constantly think of reasons that their theropod is bigger or stronger while bashing the other. The feud probably started because the ''Spinosaurus'' replaced the ''T. rex'' in ''Film/JurassicParkIII''. Things get worse when the carcharodontosaur ''[[TakeAThirdOption Giganotosaurus]]'' gets involved, with fanboys practically doing the same thing as the other two carnivores. In fact, it would probably extend to a battle of ''any'' of the largest carnivorous dinosaurs.

** Then there's the battle of the largest marine predators, giant shark ''Carcharodon megalodon'' and the pliosaur ''Liopleurodon'' (even though the latter wasn't even that big, about 7 metres long, because ''Franchise/WalkingWithDinosaurs'' [[CriticalResearchFailure based the 25 metre long depiction off incredibly fragmentary remains]]).

** In UsefulNotes/{{Chicago}}, there are innumerable claimants to the title of best Chicago deep dish pizza. A few places are more popular than others, but the only thing that most aficionados can agree on is that Pizzeria Uno--the unquestioned originator of the modern style--is no longer in the running (having turned into a national chain). Subverted in that the city's most popular pizza is a thin-crust variety, though there are also countless claimants to the title of best pizza of that type.
** In UsefulNotes/{{Michigan}}, we get a layercake of rivalry respecting the Coney Island hot dog (a kind of chili dog that has nothing to do with the place in Brooklyn): First, there's a rivalry between Detroit-style dogs (which have a wetter chili) and Flint-style (which have a drier chili) as well as Jackson-style dogs (which claims Flint stole its recipe). Second, there's arguments within both the Detroit-style (American and Lafayette Coney Islands) and Flint-style (Angelo's and Starlite).

** Modding: Is it acceptable to replace incandescent lights with [=LEDs=] on machines built before [=LEDs=] became standard? Are [=LEDs=] too bright for use in darkened locations, such as bars and private game rooms, or do they provide much-needed light for easier viewing? Is putting decals on certain things okay? Is bringing in a decoration from another pinball machine a playful show of humor or blasphemy against the machine and its makers? How much should one spend on modding? Should one even mod a pinball machine at all?
** [[TheProblemWithLicensedGames Licensed themes]]: There are groups that desperately want unlicensed machines, there are groups who are waiting for someone to make a pinball machine with a specific theme, and there are groups who are glad to see anything made at all and appreciate it when there's a theme they like but aren't dedicated fans of. This problem came to the forefront with the release of ''Full Throttle'', the first unlicensed major release in 15 years, whose reception was lukewarm compared to surrounding releases.

* Fresh ramen vs. UsefulNotes/RamenAsDehydratedNoodles. Fans of the former look down on instant ramen for being nothing compared to fresh ramen, while fans of the later defend its comparatively super-cheap cost and availability since not everyone has the budget to spend money to go to a ramen shop or the geographical proximity to one (especially if one lives outside of Japan).

* In the dinosaur fanboy community, one of the biggest debates involves who would win in a fight between ''[[TyrannosaurusRex Tyrannosaurus]]'' and ''[[AlwaysABiggerFish Spinosaurus]]'' (two of the largest carnivorous dinosaurs), with both sides involving fanboys who constantly think of reasons that their theropod is bigger or stronger while bashing the other. The feud probably started because the ''Spinosaurus'' replaced the ''T. rex'' in ''Film/JurassicParkIII''. Things get worse when the carcharodontosaur ''[[TakeAThirdOption Giganotosaurus]]'' gets involved, with fanboys practically doing the same thing as the other two carnivores. In fact, it would probably extend to a battle of ''any'' of the largest carnivorous dinosaurs.

* There are two advocacy groups for the blind in the US: The American Council of the Blind, and the National Federation of the Blind. They have very different philosophies on how to integrate blind people into society. In general, the ACB thinks society should change to accommodate blind people, whereas the NFB thinks blind people should adapt to society as it is where possible. To outsiders, the NFB can seem radical and strident (they once campaigned against tactile currency because 'blind people can handle money just fine as is', while the ACB can seem whiny and needy. So strong is their mutual hatred that they schedule their national conventions at the same time, so you can't go to both.

** In America and especially Japan, [[UsefulNotes/KentuckyFriedChicken KFC]] VS [=McDonald's=]. To the point that various [[StupidStatementDanceMix remixes of Japanese Ronald McDonald commercials]] [[https://www.youtube.com/watch?v=XXU68uo9qUc&t=573s would frequently show Colonel Sanders]] (mascot and founder of KFC) [[TakeThat as an easy target for Ronald.]] Helps that both [=McDonald's=] and KFC are [[GermansLoveDavidHasselhoff insanely popular in Japan.]]

** And then there's [[TakeAThirdOption Dr. Pepper]].
*** The real rivalry there is Dr Pepper vs Mr Pibb.

** Said restaurant rivalry do not apply in the UsefulNotes/{{Philippines}}, where the local restaurant chain Jollibee hold the reins all over the country, and UsefulNotes/McDonalds come in second place. Burger King and Wendy's are somewhat obscure outside of major urban areas.

* UsefulNotes/KentuckyFriedChicken vs. Popeyes vs. (if applicable) Churches vs. Browns[[note]]once again, if applicable[[/note]], vs. Harolds.

** In America and especially Japan, KFC VS [=McDonalds=]. To the point that various [[StupidStatementDanceMix remixes of Japanese Ronald McDonald commercials]] [[https://www.youtube.com/watch?v=XXU68uo9qUc&t=573s would frequently show Colonel Sanders]] (mascot and founder of KFC) [[TakeThat as an easy target for Ronald.]] Helps that both [=McDonalds=] and KFC are [[GermansLoveDavidHasselhoff insanely popular in Japan.]]

** And in certain areas, both of them vs. Papa Johns. Little Caesars joins in as well. And then there's all of them versus local pizzerias.

* In the world of home improvement, the Home Depot vs. Lowe's. In northern states, Menards may be thrown in.

** America actually has more than two parties but you probably wouldn't know that since only the Democrats and Republicans get any attention. This leads to the always-painful liberal vs. conservatives.
** And within the Republican party, moderates vs. Tea Partiers. It's gotten to the point that [[DefeatMeansFriendship unity events]] are being canceled. And of course the Tea Partiers are just going to fire up the Democrats.
** And within the Democrats, it's moderates vs. progressives. The 2016 primary between UsefulNotes/HillaryClinton and Bernie Sanders was a showdown between the two. The two groups continue to snipe at each other, with each side blaming the other for Clinton's loss in the general election.

** For handguns, the pre-eminent rivalry is undoubtedly 1911 vs. Glock. They could not be more opposite: the 1911 is a single-stack, heavy, all-steel, single action only hammer-fired gun with multiple external safety features (with both a thumb and a grip safety), while Glocks are double-stack [[labelnote:note]]Single-stack Glocks didn't exist until the Glock 36 was released in 2000, and it took another 14 years before Glock came out with another single-stack model with the G42[[/labelnote]], polymer-framed, lightweight, striker-fired guns with no external safeties (it has a trigger safety, which means it only fires if the trigger is pulled all the way back). And these two models also serve as stand-ins for the larger debate between polymer vs. metal framed pistols: Despite the fact that polymer guns have taken over the firearms market for civilians, law enforcement, and military, there are still lots of people who will swear by steel only and have no time for "plastic" guns, while those on the other side look at the 1911 and its contemporaries as obsolete relics from a by-gone era.

** Leading into all of the above are the Great Caliber debates. 5.56mm or 7.62mm? 9mm or .45? .357 or .44? Speed or size? You will see fans of any popular caliber swearing by their favorites and deriding anything else as inferior.

* Not even theoretical physics is immune from this; the most famous example (currently) is proponents of string theory vs. proponents of other theories, with the latter accusing the former of playing unfalsifiable, unscientific mathematical parlour .

** In UsefulNotes/{{Chicago}}, there are innumerable claimants to the title of best Chicago deep dish pizza. A few places are more popular than others, but the only thing that most aficionados can agree on is that Pizzeria Uno--the unquestioned originator of the modern style--is no longer in the running (having turned into a national chain).

Second, there's arguments within both the Detroit-style (American and Lafayette Coney Islands) and Flint-style (Angelo's and Starlite).

* Krispy Kreme versus Dunkin Donuts is a common debate. Don't get Starbucks or Tim Hortons into the argument or you'll really have a brawl. And heaven forbid that your local coffee shops get in the mix.

** Who are united, however, against foolish people who insist the drinks taste the same.[[note]]While they are pretty similar, Coke has a slightly stronger vanilla flavor while Pepsi is more citrusy.[//note]]

** Who are united, however, against foolish people who insist the drinks taste the same.
