Ron, perhaps I did miss your point, but if so, you are likewise missing mine. ;-)

I agree with you 100% when you say: "Hitler abused religion--as I said. Religion itself is not to blame"

Exactly. That's what I'm saying! Religion itself is never to blame for the wrongful things done in its name. It is people who abuse religion who are to blame for those wrongful things.

Anyway my original point that started off our (yours and my) discussion was simply this: that you can hold up Stalin and Mao as leaders of atheistic movements which totally denied religion on principle and killed a lot of people while so doing...but you can't do that with Hitler or the Nazis, because they were not, by definition, an atheistic movement.
