However, I'm not faulting atheism just the claim they don't start troubles. The non-belief is said to avoid war. Not so. Is it a wee bit immoral to fudge facts by "it's only once, it's just for freedom"
?

The strongest atheist was Stalin "steel". He broke down church buildings faster than Superman . He invaded Poland twice and Finland, East Germany and Czechoslovakia once. Putin is Orthodox , invaded Ukraine and is good friends with Stalin.

Lefty One,

Hitler was not a devout Catholic. Though he self identified as a Catholic (probably for political reasons) he did not actually believe in the existence of God. You might say he was a closet atheist, though he didn't try very hard to hide it either.

Atheists could start quoting Christopher Hitchens who wrote;

Religion is “the most base and contemptible of all the forms assumed by egotism and stupidity.”

and;

I find something repulsive in the idea of vicarious redemption.
I would not throw my numberless sins on to a scapegoat and expect them to pass from me; we rightly sneer at the barbaric societies that practice this unpleasantness in its literal form. There is no value in the vicarious gesture anyway.
As Thomas Paine pointed out, you may if you wish take on a debt, or even offer to take his place in prison. That would be self-sacrificing. But you may not a assume his actual crimes as if they were your own; for one thing you didn't commit them and might have died rather than do so; for another this impossible action would rob him of individual responsibility.
The whole apparatus of absolution and forgiveness strikes me as positively immoral, while the concept of revealed truth degrades the whole concept of free intelligence by purportedly relieving us of the hard task of working out ethical principles for ourselves.
Christopher Hitchens - Letters to a Young Contrarian –Ch. 9 P5

Good cut and paste.
You wouldn't put Soviet Russia and Mao's red Guards in the stupid basket?
You ( or your lofty author) say the scape-goat carried personal faults? And personal errors of all humans were carried in the implied Biblical sacrifice? Why ?

Since we're quoting. Here are some more inspiring quotes from well-known atheists:

"My concern with religion is that it allows us by the millions to believe what only lunatics or idiots could believe on their own." - Sam Harris

"Tell a devout Christian that his wife is cheating on him, or that frozen yogurt can make a man invisible, and he is likely to require as much evidence as anyone else, and to be persuaded only to the extent that you give it. Tell him that the book he keeps by his bed was written by an invisible deity who will punish him with fire for eternity if he fails to accept its every incredible claim about the universe, and he seems to require no evidence whatsoever." - Sam Harris

"I don't think the 9/11 attacks taught us anything we didn't already know about religion. It has long been obvious - even to the deeply religious - that religious fanaticism is an extremely dangerous deranger of otherwise sane and goodhearted people." - Dan Dennett

And from the only atheists theists seem to set in their sights:

"I am against religion because it teaches us to be satisfied with not understanding the world." - Richard Dawkins

"Religion is about turning untested belief into unshakable truth through the power of institutions and the passage of time." - Richard Dawkins

Beautiful stuff.
