both-sides
Explanation
The Joke
The comic is titled "Thing I Hate: Conflating Obnoxiousness with Honesty." A bearded man proudly announces "My blog posts piss off BOTH sides," and his friend responds "You must be doing something right then." The bearded man then reveals his actual position: "I'm an advocate for replacing all firewood with hamsters." The friend's expression shifts to concern.
The comic skewers the common rhetorical move where someone claims that angering "both sides" of a debate is proof that they're bravely speaking truth. This is a popular self-congratulatory stance online, where pundits and bloggers wear bipartisan outrage as a badge of honor, as if being disliked by everyone automatically means you're correct. The comic demolishes this logic by showing that there's a much simpler explanation for universal anger: the person's position might just be genuinely terrible.
The Humor
The humor is in the perfectly chosen absurd example. "Replacing all firewood with hamsters" is a position that would indeed anger everyone across the political spectrum -- not because it's a brave centrist truth-bomb, but because it's insane. The friend's initial validation ("You must be doing something right") represents how readily people accept the "both sides hate me, therefore I'm right" fallacy, making his subsequent realization all the more satisfying. It's a sharp critique of the "radical centrist" self-image that confuses being contrarian with being insightful.
