Your question is a bit bizarre. I suggest you look in just about any history book if you don't know the answer.
Were all of the Nazis and their collaboraters unbaptized ?
You've got to be kidding! How many of their collaboraters were Jews?
It's real simple mr. vet. You have to twist and stretch and use a hammer to make history fit the sick Christian-Nazi connection, but you only have to turn on the news to see who is really bent on the extermination of the Jews. You'd best turn your attention to them. AND- if you think the mere act of baptism makes a person a Christian, then most Americans are Christian (by your definition) and Israel's best friend is a Christian nation.
I don't agree that America is still a Christian nation, but either baptism makes Christians or it does not. If it does, then Israel needs American Christians. If it does not, then your Nazi-Christian connection is an atagonistic lie.
