One last thought on the expulsions, they were largely women, children and old men who were forced from their homes and sent to relocation camps elsewhere in Germany. Some of the relocation camps didn’t close until the late 50’s. To this day, these people are considered foreigners in Germany. Many of these folks were from the far eastern parts of Germany and were relocated to Bavaria and other parts of what was then West Germany (largely the American and British sectors). They were culturally different from the people around them and they were largely kept on the outside of the local German culture. They’re more assimilated today but the first couple of generations were very much foreigners in West Germany.
When they weren’t killed. Nazis killed Jews. The question is why. Because of Luther’s writings? Or because as nominal Catholics whose church practiced anti-semitism up to WWII they learned it there? Or because the were Nazis, eugenicists/Darwinists scapegoating the ‘lesser races who conspired against Germany’. History and Christianity makes me say it was because they were Nazis, that’s what Nazis did. Since the Lutheran church didn’t subscribe to Luther’s thoughts on these matters, blaming them seems stupid. If one is to blame a church, (I don’t) it seems that a church which practiced this type of behavior for over a millenia might have to shoulder that blame. Especially considering the relatively recent exercises of anti-semitism and the company that Church has kept over the recent decades.
