There has been a continuing debate between atheists and Christians about the Christian claim that Hitler and his Nazi party were the natural culmination of Darwinism. I’ve dealt with this in my own debate with a Christian that you can read here and here.
PZ Myers has an nice refutation of this whole notion of Hitler being a Darwinist. There is also a very well written article at pilly.com by Faye Flam, A Scientist Responds to the Charge that Darwin’s Theory Obliterated Morality, that deals with it beautifully. Go read both of them. They show up the lies that Christian apologists are constantly telling in their efforts to try to bury the truth of evolution.
