One example of how races differ: The current controversy over Reverend Wright reveals an important racial difference. Wright will scream something about white scientists inventing AIDS to kill black people, and this really disturbs whites, but black folks explain that the man is just blowing off some steam. It's just a good performance. When the man is done, we can go home, eat dinner, and watch the ballgame. Black American anger at its worst produces a handful of sorry bad asses with berets and leather jackets.
If a white man gives speeches like that, and large crowds gather, especially if they are young men sporting paramilitary attire, you had better pack a bag and get the hell out of Dodge ASAP.
