I'm personally glad it blew up, and I'm glad he responded how he did. He needs to grow the hell up and really really learn that speech that incites and perpetuates racial hatred is simply not acceptable. The fact that he bought into it at least enough to keep going back to that church and keep listening to that pastor is disturbing, but he is a leader of this country and I won't hold a learning experience against him.
Hopefully he and his followers who have responded to and encouraged that sort of racially inflammatory sermon will grow up and quit perpetuating racially divisive philosophy and speech.
