White supremacy is the notion that people of fair skin and Northern European descent are superior in various ways to people with darker skin from other parts of the world. White supremacy is espoused by organizations such as the Ku Klux Klan, Posse Comitatus, Aryan Nation, the Identity Church Movement and neo-Nazis. Some white supremacists couch their beliefs in terms of white pride, saying that they are not against other races, only that they are for the white race. Others are less circumspect, openly denouncing dark-skinned people as pre-Adamic mud races who lack souls, and decrying Jews as the spawn of Satan. Some white supremacists even claim that the lost tribes of Israel scattered across Europe and that white people, not the Jews, are the true children of Israel.
White supremacy appeals to people who are frightened by social and cultural change, giving them a target on which to focus their frustrations.
