These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Mallard Fillmore
Anvilicious: It's rare to find a strip that doesn't fit this trope.
Don't Shoot the Message: To some conservatives (and even some centrists), Tinsley's viewpoints are actually quite reasonable, but his method of delivery tends to distort them so horribly that they despise the strip anyway.
Dude, Not Funny!: It's thankfully rare, but Tinsley occasionally goes beyond being merely annoying or tasteless and makes some jibes (they really can't be called "jokes") that will have you saying "What the Hell, Hero?" if you like him and howling for his blood if you don't. He once, for example, basically called California Senator Barbara Boxer a neo-segregationist on zero evidence. Similarly, he made an innuendo (hell, it was more of a blatant declaration) that Barack Obama wanted to euthanize the elderly. The fact that Sarah Palin had already made that accusation was no excuse. Then there was the time King Features decided to support Breast Cancer research by asking all of their participating strips to color their strips pink on Sunday. Most did, a few didn't, My Cage satirized the silliness of the idea...and Mallard Fillmore insulted breast cancer patients. Because there is no fairness in the universe, My Cage was cancelled a week later yet Mallard Fillmore continues to run.
Every January, Tinsley "subtly" complains about the mere existence of Martin Luther King Day by instead having his readers complain that he didn't cover "Squirrel Appreciation Day." It crosses into this territory when in 2013, his strip called the complainers (i.e. metaphors for black people) to rodents.
Informed Real Life Fame: Tinsley did a week-long series of strips promoting the drafting of conservative economist Walter E. Williams as the 2008 Republican presidential nominee. In the strips, he depicted the groundswell of popular support for Williams' drafting as being so huge that it causes a frightened Howard Dean (who was Chairman of the DNC at the time) to throw a tantrum out of frustration. In reality, Williams was little-known other than by hardcore listeners of the Rush Limbaugh Show where he sometimes guest-hosted when Limbaugh was on vacation.
There's been so much negativity and vitriol whenever the comic is discussed on The Comics Curmudgeon that it is now taboo to talk about it - one of the few strips to have a blanket ban.
Unfortunate Implications: Tinsley did not take kindly to a parody strip done for Jon Stewart's America (The Book). He responded by dedicating several actual strips to complaining about Stewart "stealing" his work, culminating with a rather disturbing Jewish caricature of Stewart◊ proclaiming himself a pedophile. Tinsley (who apparently does not grasp the idea of "satire") did not get the overall joke, as the strip was on a page with other comic parodies, including a similar mocking of rival strip Doonesbury (along the same lines as its too political and unfunny) and even Peanuts (which, of course, was never a political strip). Incidentally, the Fillmore parody wasn't drawn or written by Stewart himself, but by Maria Schneider (a cartoonist who also writes for The Onion).
Tinsley's response to the controversy? "honestly, I didn't even know Jon Stewart was Jewish."
Tinsley's issue wasn't so much that his comic was parodied by Stewart but rather that Stewart didn't subsequently invite him on The Daily Show like other famous conservatives. Which naturally justifies insinuating him to be a pedophile.
