John Woodmorappe reviewed a book by Jerry Bergman called Hitler and the Nazi Darwinian Worldview. The page numbers come from that book:
To understand fully what Hitler really thought about Christianity, one has to examine what he said in private to trusted staff. Alan Bullock quotes Hitler as calling Christians “filthy reptiles” taking advantage of Germany’s weaknesses, and repeating Jewish-invented fairy tales (p. 303). Historian George Constable points out that Hitler said privately that he wanted eventually to stamp out Christianity in Germany, “root and branch” (pp. 13–14). Hitler himself once said, “I myself am a heathen to the core.” (p. 57). So much for the myth that Hitler was a Christian in any way, shape, or form.
What would have happened had Germany won WWII? Interestingly, Bergman calls attention to a lengthy item, dating from the Nuremberg Trials, documented by prosecutor William Donovan, found in the Cornell University archives. Called the Nazi Master Plan, it planned the eventual elimination of churches in Germany (p. 9).
