Not having heard the jokes under "discussion" here, I cannot comment on those specifically. But overall Chappelle's message rings loud and clear (to me) that LGBTQIA+ people, at the end of the day, are still "passing", whereas a black man in that part of the USA can never present as anything other than black, and that makes a HUGE difference.
I'll let him tell it in his own words though: https://youtube.com/shorts/hac3bwgo90g
