Uhh if someone says they believe in a religion the religion can't say, "Oh no he's not with us," your whole religion is based on the idea that people believe in it, if it wasn't, it'd be a fact or a theory.
Idk if Hitler was atheist or christian or whatever, but if he believed in god, then yeah, he was a christian. If he didn't he was an atheist.
Why are we godwinning this thread anyways?
