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...
