Honestly what Hitler was regarding Christianity seems to have evolved over his lifetime, at towards the end he seemed more concerned that the churches of Germany be German than that they be Christian and had a fair amount of criticism for organized Christianity. But there's no indication at all that he didn't remain a theist his whole life or reject that Jesus was the son of God'; and the majority of Nazis were at least nominally Christian, in much the same way that the majority of Americans are at least nominally Christian.
I'm not anti-Christian. I'm anti-stupid.
