Nazism was based on Paganism, not Christianity.
How many Jews were killed by Pagan Europeans? How many by Christians, both Catholic and Orthodox, and later Lutheran and other types of Protestant?
Is there any antisemitism at all in the Eddas, the Sagas, the Niebelunglied, etc.? No, the Odinists weren't even aware of the Jews' existence. Is there any antisemitism in the writings of prominent Christians? [rhetorical question]
