The Nazis literally wore belt buckles that said, "Gott mit uns" meaning "God is with us." So you're completely off on that one. The authoritarian pograms by dictators and juntas who call themselves "communist" were NOT anti-religious. They did not target religious people and spare atheists. So you're wrong on that one, too.

I don't know if you're a history buff. Maybe look up the word "Crusades."

From the dawn of recorded history, religious wars have dominated mankind. All over the world still today, people of the SAME religions are killing each other because they don't follow the same sect to the same God. Catholics and Protestants. Sunnis and Shiites.

I could write for hours about how wrong you are.
