I agree Ebbie that the healthy viewpoint is to look at ourselves, and not waste time judging. It also seems to me (from the descriptions) that he lashed out at someone, not because they were black, but because he was full of anger, released in their direction (they were the catalysts.) The racist words were used as a weapon of choice, for maximum impact. Possible, anyway. Far worse racists in the world, I'm sure, who never use the N word or other unpleasant epithets.
