“Atheist have done far worse in history than "christians". : Prove it. You already failed in a previous attempt.

“But the point is, is when christian do things that are "bad" they do so in-spite of there beliefs”: Because their belief is more accurate description.

“ while atheist have no reason not to, and as hitler/darwin said are not being consistent with evolution if they pretend there are moral right and wrongs.” Hitler was a Christian, so were the rulers of Europe during the slavery trade, the colonisation of all continents, and most of the famines created by their greed.
Why do you insist in claim you can’t back-up with evidences? Er, you have no choice, I know…
