That's true, but none of them stood up on stage for an HBO special saying that, also there have always been Black people in the neighborhood who thought they were good because they had 1 more dollar in their pockets than their neighbor. Fact is no matter where you stand in the Black community, we will all be considered "n1ggas or n1ggers" in white society. Nobody Black should take pleasure in the demise of other Blacks, but we do. Chris Rock realized that no matter what, no matter how much money or prestige, we will still be thought as "n1ggas". His routine would've had way more impact if he said that in the end, instead of just saying "I love Black people, but I hate n1ggas"
You take the blue collar or hard working Black person, and you take a thug or a hoodrat, put them in a lineup and ask a white person which one they think is the "n1gga", they are going to look at you and say "all of them". And that's why he's not doing the routine anymore, if he didn't think he went beyond a joke, he'd still be doing it.
