It interested me the way the poster you quoted conflated not simply Nazism and Christianity, but WW I Germany and Nazi Germany. The irony is, Germany during WW I had a relatively good reputation regarding its treatment of its Jewish citizens, contrasted with France with its recent "Dreyfus affair," and Russia with its anti-Jewish pogroms. In fact, German forces on the Eastern Front in WW I often had to take care of Jewish refugees who had fled from Russian held territory, often the result of persecution from Russians who suspected them of sympathy for Germany. The man in charge of homefront logistics for the German war effort in WW I, Walther Rathenau, was also Jewish.
