Chappelle's next-level satire, which may not have come across if you're not American, is that Blacks and Jews have a shared history of racism/persecution in the U.S. Indeed, I believe most whites who protested with blacks in the 1960s were Jews. The odd difference is, how do I put this, the smart blacks are behind held back by the stereotypes of their dumb-black relatives while the dumb Jews are being held back by the stereotypes of money-making (cheating) smart Jews.
So Chappelle is pointing out the huge betrayal of the Jews to Blacks. That they would take any black (like Kanye) and make him the enemy of the Jews. As if Blacks have now arrived just because one of them is a billionaire. That they are to be lumped in with white antisemites.
Also, you talk about Western Christendom but that's separate from these two groups--ambitious blacks and Jews. Both are completely secular. Yes, both have their religious relations, so to speak, but they avoid them.
Not sure if any of this makes sense or should ;)
