I have seen a lot of this and in my more ignorant days, committed some of it. The problem is that too many of the common and convenient ways that white culture deals with the problem of race are in fact racist, or just oblivious. Given how rife such a conversation would be, I prefer to avoid them except in relatively sterile settings such as this. But if you really want to get it on, I recommend checking out Prof. Tommy Curry’s radiocasts. Linkies forthcoming.
