Sorry, but trying to equate Hitler in any way, shape or form with Christianity is too much of a stretch for me. By the way, Stalin got all his formal education in the Tiflis theological seminary where he studied for the Orthodox priesthood. They said he was a great vocalist in the choir. I'd put the two of them in the same category. Before Hitler became psychotic he was all things to all men in the Weimar Republic - his way of getting the vote. If he needed the Jewish vote to close the margin he'd probably have said he only appeared anti-Semitic because he needed the racist vote - and Mein Kampf was taken out of context.
I'm not sure why you used the word equate, or what you were sorry for. Anyway, you wrote:
the fact is that Lenin himself wrote about Darwin's compatibility with the Marxist ideology.
Hitler did the same with Christianity, so you can't cite one in support of your argument, but discard the other.
