* UltimateShowdownOfUltimateDestiny debates produce fuel for flame wars without fail, particularly because fans of some popular pairings, such as StarWars vs. Franchise/StarTrek, treat them as SeriousBusiness indeed (there are whole websites and online communities devoted to Wars vs. Trek, for example).
* Parodied hilariously by ''Website/CollegeHumor'' in [[http://www.collegehumor.com/video/3980096/we-didnt-start-the-flame-war this video]]. Which has, ironically, started flame wars in Website/YouTube comments on "We Didn't Start the Fire" between College Humor viewers and Billy Joel fans.
* Half the fun of visiting [[ImageBoards 4chan]], where it tends to vary between "Flame War" and "{{Troll}} War".
* A great, and relatively new one, is a the Digg.com vs Reddit.com war. As well as Reddit vs 9Gag
** And whatever you do don't compare any of them to 4chan or claim they're ''better'' than 4chan. [[YouHaveBeenWarned Just don't do it.]]
* GameFAQs' "Adult Swim" Board has one major rule (above even the site's rules), saying ANYTHING about TimAndEric is a declaration of war.
** Similarly, go to the VideoGame/TalesOfSymphonia board and make a topic about who Lloyd would be with (Lloyd x any character who appeared in the game).
* The mere mention of a certain girl whose name refers to a three dimensional container with six sides warrants your being perma-banned from the internet, and the planet. This statement may have been enough...
** ...IrmaVonCube?
** ...[[spoiler:Boxxy]]?
** [[TooDumbToLive Cube?]]
* Here's something that you might want to try out. Look for a forum (preferably showbiz-related) that has a fairly large Filipino membership. Create a thread titled "[[http://en.wikipedia.org/wiki/ABS_CBN Kapamilya]] or [[http://en.wikipedia.org/wiki/GMA_Network Kapuso]]?" Talk about network ratings, and watch Armageddon unfold right before your eyes.
* A little broad to fit anywhere else, but digital piracy as a whole. There's a reason the [[DigitalPiracyIsEvil page pertaining to the issue]] has been locked out of real life examples.
* Can sexual or violent genres of {{literature}}, {{anime}}, WesternAnimation, etc. have a bad influence on the development young children or not? It's best not to ask this question on ''any'' social network; it's as good as declaring war.
* Everything else. Even if it seems impossible to debate. [[InsaneTrollLogic Especially if it seems impossible to debate.]]
