Who cares what lies he spewed? He was insane. Surely you understand that a madman seeking power will say anything if he thinks he can obtain his objective. Hillary claims she has a strong interest in the welfare of children. Do you believe her too? The simple fact is that tyrants tell lies. Hitler was very good at that. (Clinton too.)
Hitler had a stronger interest in (and knowledge of) art and architecture than biology (of which he obviously knew nothing). Would you condemn architecture because Hitler fancied himself to be an amateur architect? Mein Kampf is full of endless blather about hygene and excercise for the youth. You want to condemn that too?
No, you don't pick on his concern for hygene, or his architecture, or his vegetarianism, or even his astrology. Only evolution. I understand that you're a creationist. Fine with me. But the study of biology doesn't make anyone a follower of Hitler.
