My point is that there are many more important influences on Nazi belief than evolution and Nietzsche. These are being completely ignored by those trying to place the blame on evolutionary theory.
For instance Gobineau's ideas of Aryan superiority:

The companion article on Gobineau is at:

Note the publication dates.
We haven't even got to other influences such as Richard Wagner, the nationalistic and anti-semitic composer whose music was loved by Hitler.
Anyone who was really concerned about the Holocaust would not spend their time attacking minor influences. What disgusts me is people who think that attacking views they personally dislike is more important than the suffering of the victims.
