It was an essential belief in Nazi ideology that survival of the fittest pertained to the aryan race. Hitler was a Darwinist. Whether all Nazis were Darwinists or not is rather disingenuous: not all Democrats are pro-choice, but the party is and more than likely, so are most members.

Actually, although we never bring it up unless someone on your side of the debate raises this issue, Hitler was a creationist:

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 was a Theosophist. His views on race had nothing to do with "survival of the fittest." Indeed, his views of race were colored by a particular mythology that the Aryan people were created the most perfect people on Earth and that other races -- "mongrel races" -- were degenerate offshoots of this race. In some versions of the mythos, some of the "subraces" were created after the Aryans by Satan, who used inferior materials; hence the references in neo-Nazi propaganda to "mud people."
