In any event....It really doesn't matter what Hitler's beliefs were. I am not claiming he was an atheist, but I am claiming that his regime committed millions of murders not based on any religion at all, but on evolution and yes atheistic leanings. What they attempted to accomplish was straight out or Darwin's OOTS. My opinion of course.
Regarding your contention that religion is accountable for more deaths ( if that is indeed your stance)....please read this book " Death by Government", in which the author actually documents and numbers exactly how many people have been killed by religion versus non-religion. It is a good read no matter how you feel. You'll thank me later.
