Actually, "we're" more afraid of nut religions, most especially atheism, being tied to some nut cases. Christian nut cases, including some of the darkest years of the Catholic church, only killed about 300,000 whereas other pagan religion nut cases, most especially atheistic, have killed over 14 million in this century alone.

You seem to be confusing "Communist" for "atheist." Ain't the same thing. Atheists believe there is no god. Commies believe the State is god, just with a different name.
Just think, if there were none, there would be no deaths tied to religion or someones view of what God wants them to do.....
