Hitler was an Atheist. He and his Nazi gang gassed 5 million Catholics. The Catholic Church was basically shut down by 1942, with Mein Kampf replacing the Bible, statuary and imagery removed and the only items allowed on display inside a Catholic church were a picture of Der Fuehrer and a sword. Long before 1942 Catholic priests and bishops were being murdered, Church newsletters and books had been declared illegal, sermons were monitored for their support of the Nazi regime, and the seminaries had been emptied. Hitler famously stated that Catholics must be killed since they 'opposed science', meaning Evolution and Darwinian 'survival of the fittest, by natural selection'. Hitler was a Darwinian Atheist.
“In Germany, the leaders of the eugenics movement, using evolution as their justification, caused sterilisation laws and immigration restriction laws to be enacted during the 1930s. Immigration should be limited, they said, owing to the ‘biological inferiority’ of people from southern and eastern Europe. The racism of such leaders was founded on evolution, and the German people were being prepared to regard themselves as the superior race.” Source
Eugenics, killing the sick, the 'unfit' or the 'eaters' as the Nazis derisively called the old [and thereby useless]. More than 500.000 German soldiers injured on the Eastern front were liquidated by the Nazis due to their 'unfitness'. Anyone suffering from mental illness, down's syndrome, physical 'impurities', or who were 'racially inferior' could be subjected to torture and death. Darwinian theology preaches that the 'strong' must eradicate the 'weak' in the 'natural' search for 'fitness' and 'perfection', as creatures 'evolve' better means of survival and adaptation.
“Hitler did not form his ideas in a mysterious vacuum, which is the impression that history books give us. He was instructed by the idea called ‘eugenics’, which was derived from the so-called ‘fact’ of evolution by a cousin of the originator of the scientific respectability of evolution.
As much as they wish that the general public would forget all about eugenics, evolutionists must accept the fact that their favourite idea, ‘the fact of evolution’, was the basis for eugenics, which led directly to Hitler’s death camps.”
Hitler's National Socialism is a direct result of implementing Evolutionary dogma. Magically mud became Men and 'nature' is constant warfare as random processes collude to force the fitter to dispense with the weaker. The Nazis sold their Socialist Fascism to the German public by using 'science' and 'proof' that superior races did and must exist and had a 'moral duty', to wipe out inferiors. In his book 'The Descent of Man', Darwin mused that Whites would one day by necessity, kill off Blacks and other lower-evolved hominids. Hitler simply took these ideas, which were much in vogue in the early 20th century, including eugenics and racial purity, and applied them to politics. No wonder Socialist and Atheists are so keen to distance Evolution and Marxism, from Hitlerian theology.
