Allow me to try and put your fevered mind at rest.
My beliefs are that there is a God, i believe in a Christian God. Others believe in other Gods, good for them.
Some don't believe in any God good for them too.
It's no different to raise a child to believe in God than to raise one not too, a parent has to teach a child something it's better to teach it what they know or believe.
The above mentioned tyrants were all atheists (P.S. Hitler was not enamoured with protestantism, nor was he a homosexual, a sexual sadist or a Jew all thngs said about him) if only you could admit to that. Nazism is widely described as "Neo-Darwinism" I don't hold Darwin responsible for Nazism, or Apartheid, or Segregation all based on evolutionary theory. People took his work, expanded upon and then twisted to their own political ends (same meat, different gravy).
I don't hold atheism responsible for their acts no more than hold Christ responsible for the crusades or Mohammed for the Ottoman empire.
When I look back over the last 200 years or so I can think of the Napoleonic Wars, The Imperialist wars, The American Civil War, The Crimean War, The Franco Prussian War, The Spanish American War, The Russo Japanese War, The Great War, The Chinese Civil War, The Sino Japanese War, WW2 none of these wars (and more) had anything to do with religion, which gives lie to the argument that religion causes wars. Governments cause wars and they get people to fight them, for whatever reason they can think of.
To respect someones right too believe in any God in a free country is as important to respect the rights of someone to believe in no God.
If you dislike the phrase "believe in nothing" I apologise it was merely shorthand to to refer to atheism.
