[PatrickHenry]

To be precise, Darwinism contributed to Fascism or National Socialism.

To be even more precise:

For it was by the Will of God that men were made of a certain bodily shape, were given their natures and their faculties. Whoever destroys His work wages war against God's Creation and God's Will.
-- Adolph Hitler, creationist

Discussed at Adolf Hitler's Religion.

[A. Pole]

For it was by the Will of God that men were made of a certain bodily shape, were given their natures and their faculties. Whoever destroys His work wages war against God's Creation and God's Will. -- Adolph Hitler, creationist

Hitler's god was a pantheistic god of nature, of racial competition and of struggle for survival. He was not a creationist in a Christian sense. His god was further away from Holy Trinity than Muslim Allah.
