You can't discriminate against Nazi's. Unlike blacks, and Palestinians, and women and gays, they are not born into an oppressed group. They chose to become nasty minded little weasels, and if left unchecked, make life worse for those who really are the victims of discrimination. Yes, as Chris says 'they're all individuals with ideas', and those ideas make the world even more unjust and violent. I'm sorry for the people of the warm and fuzzy approach to activism, but Hitler, vegetarian and animal lover though he was, would probably not have got over it if he'd just been given a big hug.
