Let me preface this by saying I’m not a fan at all of Bill Burr, but he recently went on Bill Maher’s show, and said he was with the students. He’s also said some inflammatory things in the past, so I’m not sure. Are we cool with Bill Burr, now?
I think in general he leans more left than he lets on if that’s what you mean.
His podcast when his wife is on (It annoys me that people would find this to be relevant credentials, but she’s a POC) shows that he has a pretty healthy world view where he talks crap a lot, but is happy to be told he’s an idiot as well, at least by her.
