You are saying he was not making any kind of serious point using humor as a way to make it. Nooo, you’re kidding right?!
Go back and listen to some of Don Rickles’ routines. He makes fun of literally every ethnic group he can think of. Blacks, Italians, Jews. But here’s the thing. Rickles never called for violence.
Chappelle is the same way. Does Chappelle’s comedy contain hidden messages? Maybe. But I will not condemn him on a “maybe”.
My advice would be to simply shun any performer whom you find offensive. I myself do not follow Chappelle. It’s because of his unnecessary vulgarity.
