You're not even listening to what I'm posting, I'm not saying he was a "bad" Christian, I'm saying he did not even believe in Christianity at all.
Evidence shows he was Christian whether you think he was "true" or not. He was a member of the Catholic church until his death, and neither of us will ever know if asked for forgiveness before death, which is all that's required to get right back into heaven's queue.
I agree there's plenty of cause for debate over his personal views on religion and I understand why religious folks would shun such a member of their camp. Perhaps you simply shouldn't have brought him up in the first place?
Ok, here are the points you make:
1. He was a member of a church
2. He could have asked for forgiveness before he died
As to 1, belonging to a church does not make you Christian, and as to 2 while he certainly could have asked for forgiveness before he died, he would have only been Christian for the remainder of his life, when, ironically he would have then committed suicide.
I shun him as a member of my "camp" for a very obvious reason, he was not Christian, and only attempted to look Christian out in public to gain acceptance. When you look at quotes from his personal life, it becomes quite clear that he was no Christian.
Actually, it was you who brought up Hitler being Christian. So, perhaps you should not have brought it up in the first place.
