In short - "Give unto Caesar that which is Caesar's, and give unto God that which is God's".<quoted text>Not that old lie.
Apart from the fact that some on the list weren't atheist (e.g. Hitler), none of them were motivated by atheism and none of them could have been restrained by (even more) religion.
Beliefs should be challenged, not held sacred.
Perhaps people who are religious and know to keep it to themselves might take it from a prominent religionist?...
"If I were a dictator, religion and state would be separate. I swear by my religion. I will die for it. But it is my personal affair. The state has nothing to do with it. The state would look after your secular welfare, health, communications, foreign relations, currency and so on, but not your or my religion. That is everybody's personal concern!
― Mohandas Karamchand Gandhi
If religion is to survive at all, it will need to be defended far better than the patently falacious comments of Lincoln, Rio and Muq. We are all essentially human and equal. We mustn't allow religion to influence politics, science, the law, morality, or education , or freedom of speech or expression,(as in the example in my post at the top of this page). Religion should never divide us,(e.g Sunni & Shia; Zionist & Islamist; religionist & atheist). That would certainly be an atheist view and religionists would do well to live by that too.
Humans are natural god-makers. Theology of one kind or another will always be a part of mankind's experience. It is a way to expunge moth eaten dogmas and ceremonies, both religious and scientific, to encounter the universe through our eyes and to try again to push against our recognized boundaries.
