except that no, it isn't. not even a little bit. none of his work is.
if you go back and watch all his specials since 2016 and actually listen to the context and the subtext, it's incredibly clear that:
A. he's a bit taken aback by the cultural zeitgeist of the trans movement in relation to the cultural zeitgeist of racial justice.
B. he's critical of assumptions made by trans supporters, while being supportive of being trans in a general sense.
pointing out that there is absolutely a valid question of to what extent the rest of us are obligated to participate in a trans person's self image is not transphobic... that is an incredible rhetorical point, especially since he asks it without providing any kind of answer.
it is a scathing observation about race in america, not bigotry against trans people, to point out that the monumental gains in the cultural sphere that have been made by the trans community in the last 20 years is very likely in no small part due to the fact that prominent white men are the ones doing it that get the most recognition from the public.
so many websites seem really committed to the idea of pretending that these specials are 'transphobic' (the AVClub is another one that just keeps hammering that dead horse at every possible opportunity) and it's kind of revealing that 'lack of catering' is being so conflated with 'insensitivity'.
nothing chapelle has had in any of these specials slags on trans people in any way, he's just not coddling to their position - i personally think that there's an interesting abstract there, about whether strict militant insistence that whatever trans people say must be accepted as reality is the *only* way to be supportive of trans rights.
