Personally, I think once society can laugh at its own stupidity, we will be better for it. Once people can say, "that's a stupid joke", instead of "that's a racist joke", we'll know we are there.
Chappelle is funny. I like Jeff Foxworthy too. I used to like Margaret Cho but she's turned into an unfunny pig IMHO. Laughing is better than crying.
That was Chris Rock.
