From what I've read from several books about the Third Reich, the Nazis were strongly already heading away from Christianity anyway, especially with Adolf Hitler's strong obsession with the occult.
Why do you think there was considerable interest during the Nazi era to bring back the old Norse gods? Small wonder why Richard Wagner's Ring cycle of operas was so prominently publicized--and why Wagner's descendants are still trying to live it down.
Old news yes, but not very well known or publicized. You can scan entire textbooks and not find it, spend semesters listening to history lectures in colleges, watch hours of History/Discovery/Learning and never hear it. On the internet, even an offhand mention that Nazis were anti-Christian will get you thousands of bytes of prepared text dumps attempting to prove the Nazis were Christian offshoots.
Both, JFK and Hitler were 'Patsies'.
