The Richards outburst doesn't bother me that much. He got pissed off and decided (stupidly, quite possibly drunkenly) on the spur of the moment to attack people in what he thought would be the most offensive way possible. Vulgar and juvenile, but not intrinsically different than if he had, say, shouted "your mother's a whore!" People do shit like this. I actually doubt very much that he's a racist.
