To what extent does Mencia (as a blatant example) make jokes aimed at bringing discussions of race to the forefront, and to what extent does he make such jokes because he also happens to be a bigot*, but since he's a Latino bigot, he can get away with it?

I don't know the answer (and I reckon that's something like what you're asking, too).

* I'm not saying he is, by the way.
