Imagine if a white comic said the same thing about poor black people. Angry mobs (of white people) would lynch him.
Did you watch the comedy special? It was hilarious. Many comedies poke fun at racial divides or differences. I wouldn't take anything they say at face value. Comedians obviously exaggerate or say things in a certain way to draw attention to irony and make things funnier.
It's when they go on Twitter that they reveal who they truly are.
