Comedy has become an act of airing social grievances (maybe always has been but definitely amplified these days) and thus peoples inherently political social grievances are going to sort them into their respective camps.

If the problems you’re facing and exposing are “the big man is keeping me down” you’re gonna find solidarity in that message and if your problems are “those people are gross and I don’t like them” only other people who have similar obsession with ordering society into groups of chosen people vs undesirables will respond to your message.
