These memes aren't criticizing or satirizing Chappelle or Crowder, they use them to make completely unrelated points. Which is just free exposure and cultural relevance for people who already have too much of both.

I just don't thing that giving attention to those people is good unless it's specifically about mocking them. Not like the second thing doesn't do the same thing as first one but yeah... Personal opinions and stuff.

Edit: also I don't get how anyone can be fine with having transphobes in their regular memes. Each your laugh will be accompanied by disgust of seeing a pos alongside the text.
