A black trans person would absolutely have a hard time passing, but Dave's point is that being open about one's LGBTQIA+ status is a choice (arguably not much of one, except that people do it so... it CAN be put away, when someone is ready to "pass").

Mainly he's saying that black people are people too, and should be considered as such. He has pointed out how unfair he considers the situation that when white gay men wanted marriage equality, a Supreme Court decision came something like 10 years after the major push started, with everyone in Hollywood backing that. Meanwhile, black people have been waiting for equal rights in the USA for 400+ years, and it's like "when is it our turn?"

It seems all too convenient for white men who are also gay or trans or whatever to call it quits when they get theirs, leaving POC behind in the dust, again.

I find like many people judge him without ever even listening to his material, so of course cannot really understand it.
