He might not be directly responsible in this sad occurrence but I don't think anyone could convincingly argue that Chappelle isn't part of the larger problem.
Precisely. Distributing blame in the face of suicide is frequently difficult, counterproductive, and misguided. Rarely is anyone directly responsible, rarely does any attempt to make someone directly responsible capture the tragic circumstances that might lead someone to make such a decision. In this case, there's no evidence Chappelle had any role
at all, much less a role that would make him deserving of blame.
Still, it's worth bringing him up. Do the people who find it "disgusting" to see his name being thrown around here not think that some of his recent jokes have been transphobic? Do they not realize the direct result of making transphobic jokes is to make the world less equitable for trans people? Do they think that having and supporting a trans friend somehow makes his transphobia okay?
When a trans person who was best known for coming up in one of his transphobic specials commits suicide, that merely makes the need to do
way better all the more real in a way that should be intuitive to anyone.
Throwing out RIPs without reflecting on the obvious isn't somehow being honorable.
