I exempt USSR, Stalinism, Pol Pot, China
and other totalitarian regimes because a real atheist would never tolerate them.

But I could feel the same way about a real Christian. I think both the real Christian and the real atheist could have objections.= to some things that happen in the world.

I might think you are wrong in your (I'm reading it that way) atheist belief (ie that there is no deity) but would I want to start a "Holy War" with you over this differences? My answer is no.

You are aware of Christianity of Bhuddism, of Islam, of atheism, and probably more belief systems than I know of I can put forward proposals and state my own lead me to wanting to keep trying (and failing) with Christ but I can not make you anything, nor should I.

Awareness of the different systems is one thing. Which one you take is yours alone.
