There has never been anything insightful or righteous about Chapelle's dismissal of lgbt people's fight to secure their rights. He doesn't get a free pass to be a bigot because black people are an oppressed group too, the comparison is sort of dishonest.

What Chapelle is trying to do is secure his place in a heirarchy, by punching down he's defending the very system and mode of thought that has oppressed both black and lgbt people (which are not mutually exclusive groups as he must frame it for his logic to work). Ironically, he is doing exactly what a patriarchal white supremacist would want; to divide oppressed minorities and weaken their efforts for equality. And he's using much of the same rhetorical fallacies that have been used to promote right-wing political philosophy.

Chapelle has always been a profoundly dishonest person, it's just become more apparent now that he's trying to speak on experiences he clearly knows little to nothing about outside the stereotypes he's been too intellectually lazy to disabuse himself of.

For satirical comedy to be good there has to be an element of truth at the center, with Chapelle its simply a kernel of hate. It's readily apparent to the people he's targeting.
