I'll defend him - on the grounds that I think that we should value free speech.
I might be alone in this, but I am getting tired of the mass hysteria that follows any comment that is not considered PC.
People regularly make statements / claims that I totally disagree with or find distasteful, but that is the price you pay for a free society. Obviously, there are limits (personal threats, for example), but personally I don't think that the comments in question come near those.
That said, I'm willing to bet that he knew exactly the reaction his words would cause, and is relishing the publicity!
