Rosetree, not ALL Nazis were atheists. And no one was killed in the name of atheism. Can't say the same of Christianity. One only has to look in the bible to see how many were killed on orders of "God" and in the name of "God".
The Hitler, Stalin, Pol Pot excuse doesn't make the grade for none of them killed in the name of atheism.
Anyway, we can't just ignore the history prior to the rise of Nazism: Crusades, Inquisitions, Colonization, Genocide, etc.
