Hitler's Germany was 95 percent Christian

 //[T]he Germany that Hitler led remained 95 percent Christian and 55 percent Protestant. Most of the Germans who welcomed Hitler's rise to power-who saw Jews increasingly deprived of their rights, who witnessed the burning synagogues and broken glass of Kristallnacht, who watched the removal of Jews from German soil, who listened to rumors of the annihilation of Jews in Poland and Russia-were self-professed Christians. Most of the actual perpetrators-members of the SS and of the reserve police battalions, the shooters and the scientists, those who ran the trains and those who ran the camps-received religious training in the Protestant or Catholic tradition.//
