Catholics today like to distance themselves from Hitler, Understandably, But as much as they would like to rewrite history - much like they do in child abuse cases - The fact remains that Hitler, While in power, was a devout Catholic who visited the pope, and after his fall from power wrote many times in "The Nazi Bible" (Mein Kampf) about his christian faith and how he sympathised with jesus' fight against "Jewish poison". His faith in god and religion even lead him to put "Gotten Mituns" on every Nazi soldiers belt buckle, Which translates in to English as "God With Us".
Doesn't sound like the actions of an Atheist to me.
If you have a copy of Mein Kampf laying around you may be interested in looking up the follow quotes;
I believe today that my conduct is in accordance with the will of the Almighty Creator.p. 46
And the founder of Christianity [Jesus] made no secret indeed of his estimation of the Jewish people. When He found it necessary, He drove those enemies of the human race out of the Temple of Godp.174
In 1922 he published "My New Order" and in that stated;
My feeling as a Christian points me to my Lord and Savior as a fighter. It points me to the man who once in loneliness, surrounded only by a few followers, recognized these Jews for what they were and summoned men to fight against them
In boundless love as a Christian and as a man I read through the passage which tells us how the Lord at last rose in His might and seized the scourge to drive out of the Temple the brood of vipers and adders. How terrific was his fight against the Jewish poison
When I go out in the morning and see these men standing in their queues and look into their pinched faces, then I believe I would be no Christian, but a very devil, if I felt no pity for them, if I did not, as did our Lord two thousand years ago, turn against those [Jews] by whom today this poor people are plundered and exploited
There are many more occasions when Hitler made his faith in God and Jesus clear, But we could be here all day. As atheists it is important that we challenge every falsehood perpetuated by the religious and we have to challenge every attempt by them to rewrite history.
