And was defeated by a coalition of Christian states, and to this day the German people remain (needlessly) disgraced and humiliated by that episode of their past.
The Nazis represented the brief triumph of the animal (evolutionary) instinct of nationalism over the Christian tenet of compassion. But still, all of Germany's (Christian) neighbours forgave her, giving us the European Union.
I agree that Germans have nothing at all to be ashamed of.
The Nazis were defeated by a coalition of (largely) Christians, other religions (Hindus under Britsh Control, North African and Middle Eastern states/colonies included Jews and Muslims,) and non-religious states (I don't think you'll find that the USSR were formally religious at least, and informally included groups of several denominations and religions partic. in the Caucasus), including one major player who wanted nothing to do with it until directly attacked by an Axis power a few years into the war.
The same European Christians watched while the Sudetenland and similar shit went on. I get that, people were tired. But he had the Jewish people running right from the start, and for fundamentally evil reasons. And the society that spawned him did not do enough enough to help his victims at the time. This doesn't make Christian societies baddies. They're not. But if one is to blame particular religions for the behaviour of the societies in which they are dominant, it ain't so black and white.
