I never said the ideological basis for Nazism and that validated it was limited to Christianity. I also think the Nazis misinterpreted Nietzsche. Have you ever read The Case of Wagner: A Musicians' Problem? In it Nietzsche rebukes Wagner and his anti-Semitism.
In your earlier post you said
From what I understand, it was believed by European Christians that the Jews were at fault because they didn't except the message of Jesus (as) or him being messiah and along with this it was believed it was the Jews whom killed him thus they were guilty of deicide. As for Martin Luther, I think initially he didn't hate the Jews but when they didn't accept the message of Jesus (as) and went on to practice their own faith he became enraged and that's when his anti-Jewish beliefs/comments started. I also agree that this anti-Jew business of the Nazis and Hitler wasn't new and was an continuation of historical European prejudice.
This plainly emphasizes Christian origins of anti-Semitism. Modern secular thinkers like Fichte, Schopenhauer, Kant and others did not believe that Jesus was the Son of God and they did not believe the Jews were under God's wrath for rejecting him. Their objections to the Jews were very different, and were based on secular reasoning.
About Nietzsche, have you read his book The Antichrist? There he argues that Christianity is false and bad, it has corrupted Europe, and he blames this on the Jews. He also describes the Jews as being master manipulators of decadence, undermining society. He objected to Wagner's anti-Semitism because it was the wrong kind of anti-Semitism.
