I think it is important to make clear that religion wasn't the motivation.<quoted text>
Ratzinger and Hilter: Both Catholic and Both Nazis!
There are masses of grounds for criticism of religion,(Zionism, Islamism, child mutilation, superstitious beliefs, ID/Creationism, Bishops in UK House of Lords, religious courts, prejudice against gays and even women, etc, etc) but religion wasn't a cause of Nazism any more than atheism drove communism.
I think Nazism was driven more by racist theories and a political (fascist type of) ideology. Its roots lay in the blame heaped on Germany for the previous world war that ended in an armistice, not (as many Germans perceived it) a defeat; and in the chaos that resulted from the perceived failure of Weimar.
