Germany was predominantly a 'christian' nation.
The propaganda by the Christian churches in regard to their role during WWII in Fascist Italy, Yugoslavia, and Nazi Germany has so conditioned their believers that most of them believe that Christianity played an honorable role at best, and only a silent role at worst. Yet there seems little recognition that the very framework of the beliefs owned by the Fascists and Nazis came from their Christian upbringing from church, school, and Christian traditions. The entire anti-Jewish and racial sentiments came not from some new philosophy or unique ideology, but rather from centuries of Christian preaching against the Jews, gypsies, and heretics. This comes especially true for European countries, for the Christian practice of crusades, inquisitions and holy wars occurred in their own backyards. Moreover, the wars conducted by Providence, approved by God, appears so often in the Bible, and practiced by Christians throughout the centuries has disciplined Christians to believe that they could engage in offensive war honorably and even worse-- morally. One must remember that the Catholic raised and Protestant conditioned Hitler took his cause of war for an expanded Germany and his fight against the Jews, for Providence's sake, and a fight for the Lord. He appealed to his fellow German Christians to put him in power and he achieved popular support. I find it unimaginable that Hitler, without this religious foundation, could have churches, politicians and citizens electing him into office, much less have acted against the Jews.
