@Heil: Whites aren't the majority of the world anymore. Even if you are a racist, you must know that starting that war would be very foolish. You'd also be upsetting a lot of whites who aren't completely mad.
No, I don't think racism is ever justified. (I voted, but I couldn't add my comment though for some reason.) Partially, race is (as I've been saying in a number of polls) an arbitrary classification created by social "norms". I see no reason why a person should be biased against another person based on what is an arbitrary classification. Certain forms of race are chosen by the individual - while certain forms are chosen external to the individual.
