The Nazi Party attracted people who were anti-Christian or indifferent or who vaguely identified with the nationalistic aspects of a cultural Christianity. These were not a “church” type of people who read a lot of theology and the Bible and could arhue the fine points of Reformation theology. And for every Nazi leader you could name who grew up in a Protestant family, you could probably find one who grew up in a Catholic family. And there were allied fascist movements, that were bad but not centered on racism, in Catholic countries.
For that saying you can be called an anti-Catholic and or an anti-Semite
