Some authors like to play favorites making one side look like the good one, while making fun of the side they don't sympathise with.
Not in this show. In this kind of show, there is no such thing as an acceptable target. They either mock all sides of an argument or none.
This trope is never played completely straight all the time due to the fact that Most Writers Are Human and all humans are biased (at least unconsciously).
This trope applies when a show doesn't have bias for any side in a given situation. However, it can be used inside the story too, when a character is particularly offensive to everybody.
A number of people have called themselves equal-opportunity offenders when defending themselves from accusations of bias, bigotry, etc, and have had varying degrees of success. The less successful ones have helped make the phrase a tad controversial, if only by association. One point raised against it, for example here, is that there are far more identifiable groups of humans than anyone could have time to offend. By selecting Scientologists or redheads for mockery and overlooking plumbers or right-handed people, the show is being less than "equal". In response, one could argue that certain groupings are naturally associated with certain stereotypes to begin with and it's not the show's fault that those prior groupings, however arbitrary they may be, are the ones that come to our minds as the "sides" in question.
In addition, it has been argued that if different groups of people are in unequal situations to begin with, then it's difficult to offend them all "the same". note Of course, this argument is itself controversial, and has been challenged as misguided, unfair, or patronizing. It's a heated debate.
For a character in universe who is willing to offend anyone, see Hates Everyone Equally.
- Haagse Harry mocks every ethnicity and political background, starting with the author's own.
- MAD Magazine had mocking commentary about any genre of movie, every political candidate, every philosophy, most celebrities, and even both sides of the Cold War (in the form of Spy vs. Spy). If there was a sacred cow to be found, they'd fire up the barbeque. In the process, the lawsuits they incurred by the targets they spoofed could fill a small law library in regards to speech and press freedoms in the USA.
- Top Gear. Especially Jeremy Clarkson. Well, mostly Jeremy Clarkson. Entirely by himself. Occasionally he does like a car. But usually he hates most of them, complains about the engineers, mocks the factory worker, and makes offensive comments about the entire population of the manufacturers country. Especially when he's on a test drive in that country. But no country is safe and even England gets the same treatment.
- Frankie Boyle will attack anyone and everyone.
- Mongrels was very free about who it set out to offend.
- S Club 7: None of the villains, even the sheriff in the Back To The 50s, single out a member of band based on race and religion. They were targeted by a villain because of their ability to foil an evil plot and inspiring others to stand-up for themselves... nothing more.
- In the Back To The 50s film, Bradley would've been an easy target because he's black and attacks against blacks by whites in the 50s were common, yet the Rockets and the sheriff only targeted him because he was willing to stand up for himself and his friends. Paul and Jo, who are WHITE, were also jailed along with Bradley and Rachel, who's Eurasian. Tina is half Indo-Guyanese, while Jon and Hannah were also white and they were fair game!
- George Carlin, moreso in his early days than his later ones. If you exist, he makes fun of you. Woman, man, black, white, left, right, didn't matter. To him, you sucked or someone was making you up.
- Lisa Lampenelli. Audience members have gotten offended when she wasn't making fun of them.
- Carlos Mencia is fond of using racial slurs for every ethnicity in existence. But his favorite is "beaner," for Hispanics.
- Monty Python's The Meaning of Life (the video game) starts with a long list of those who it will offend, working out to pretty much everybody.
- Punch-Out!! also has a long list of nationally stereotypical boxers. It also helps that two of said boxers are from the creators' home countries. (Canada for Next Level Games, and Japan for Nintendo)
- Grand Theft Auto mocks the sad state of society, the sad state of the outcasts of society, minorities, white people, gay people, straight people, transpeople, you, game developers, religion, atheists, cults, the military, the government, those against the government, foreign art, and old people. It's like Bret Easton Ellis and Todd Solondz teamed up with MAD Magazine to make gangster flicks.
- The pure evil that is Encyclopedia Dramatica. If it exists, no matter how sacred, it has a page there that's plastered with Rule34 and Shock Images.
- The Filthy Frank Show goes out of its way to deliberately make fun of a whole slew of different groups of people. Perhaps Frank himself summarized it best when he said, "Here on The Filthy Frank Show, we support prejudice equality: everyone gets shit."
- DarkMatter2525's If Muhammad Replaced Trump depicts the left wing as a horde of SJWs who hate everything Donald Trump says until they find out Muhammad said it, whereas the right wing is a horde of rednecks who agree with almost everything Trump says, but are horrified at Muhammad saying them. Trump is depicted as being able to spout out sexism, antisemitism and racism with people only being moderately surprised, and Hillary Clinton is depicted as a robot who puts too much emphasis on the fact that she is female and can get away with killing a man. Even the media is shown putting far more emphasis on the things that Trump says than Hillary murdering someone.
- South Park is famous for mocking every side in an argument. Case in point - in "Goobacks", the characters appearing on a political talk show were named "Pissed-Off White-Trash Redneck Conservative" and "Aging Hippie Liberal Douche".
- Despite complaints of biases, The creator of Family Guy has stated that his goal is to offend everyone.
- American Dad!. For example the main character and his daughter (who are right/left wing radicals respectively) are both depicted as complete hypocrites.
- Eris says this in her debut episode in The Grim Adventures of Billy & Mandy.
- Animaniacs. If it exists, it will be mocked.
- The Boondocks. Unlike the comic strip, which is unmistakably left-wing in its bias.
- The trailer for the first season of Paradise PD starts with a Long List of people who might be offended by the show and which seems to include pretty much every single group of people in existence. The show itself does its best to deliver on that promise.
