I'm interested to hear your thoughts on this. Why are you opposed to racially-based humor? I think if done well, it's much more than humor - it's commentary, it's enlightening, etc. I'm not a fan of racially-based humor that puts others down, but rather puts things into perspective. I think Chappelle was a master of this.
I am a big Louis CK fan. It's amazing to me that a white, male comedian will tackle issues like slavery, white privilege, and even gender based issues as well (rape culture). He used the n-word in a set once...not even referring to a black person, and I was surprisingly okay with that. I think again saw him on a show with Chris Rock, Jerry Seinfield, and Ricky Gervais, and he discussed using the word in his material. I'm not sure how I really feel about that.
Now I'm just rambling...
