I don't support Ron Paul but he is one of the few who gets it about what racism really is. Here are some excerpts from his piece on the subject....and, let he that isn't guilty throw the first stone. Racism blinds everyone to itself.
"Racism is simply an ugly form of collectivism, which is the mindset that views humans strictly as members of groups rather than as individuals. Racists believe that all individuals who share superficial physical characteristics are alike. As collectivists, racists think only in terms of groups....Racism will endure until we stop thinking in terms of groups and begin thinking in terms of individual liberty."
