I can't stand white supremacists. There particular brand of racism is especially disgusting. That being said, I do not condone the murder of anyone. The best way to deal with these people is to marginalize them, not kill them. Eugene Terreblanche was found beating to death at his farm in South Africa. He was the leader of the AWB (Afrikaner Weestandsbeweging), a right-wing white supremacist party that argued for a white homeland in South Africa, when the Apartheid Government was being torn down. It doesn't seem that he was murdered for his views though. Reports say that he was murdered over a wage dispute with one of his farm hands.
While I will not shed a tear over his death, I will never support anyone who murders another person under any circumstances.
