I don't think Chapelle deserves the level of hate he's received, but he was certainly punching down in his bid to play oppression Olympics. His whole point was one of being jealous that black people have a much longer road to acceptance that trans people. The problem is, because of his discomfort with the topic, his jokes fell flat, which leaves only the punching down. If you're going to cross the line, you better be funny, or people will only see malice.
