I think I half agree with you. A lot of Jon's segments were just straight up mean -- well beyond playful mockery which made him hard to watch sometimes and he got away with it because of the comedian label. Where I disagree is that he was always open about his politics and knew that his show was "serious takes with light hearted delivery" and made it a point to not talk about topics from a position of ignorance. When you hear him talk off-camera it's clear that he really cares about getting it right and saying something intelligible through the jokes.

When I listen to Joe it's different, I'm not saying he couldn't run with the bit of "I don't know nuthin' about nuthin'" and come from a place of empathy and curiosity which would be cool. But what it is in practice is "I'm a moron and you shouldn't listen to what I think I don't know what I'm talking about buttttt and then speaks authoritatively on some politically charged topic he's supposedly ignorant of."
