He seems pretty keyed into a working class mindset and background. If you listen to his interviews he talks a lot about working warehouses and stuff. He talks about that sort of northeast working class and experience in a way that seems genuine. Maybe he isn't the most refined or on top of whatever the current language of stuff is, but he seems to truly understand what working folks actually experience. Burr seems to want working people to have some dignity and tends to take shots at elites (in the Marxist sense, i.e. rich assholes) . You can always tell with comics, I can't quite nail it down but a lot of them really understand what it is to work and how much it sucks, and not in that gross way rich comics will strawman .

He seems like a good example that not all socialists (or left thinking people in general) are a bunch of online dweebs.
