I posted this in the other thread before i saw this one, so it refers to quotes in Mags selected in the "Islam" thread.
"Mags, my view may differ from other atheists here, but I do agree with you that Hitler and Stalin certainly used science not only to develop the methods of killing, but also as reasons for killing. It was bad science that would never have survived the peer review process, but they did use science, especially in eugenics. I am not as as convinced that their atheistic views were at fault for any of their terrible actions. They were control hungry and resented RELIGION and the power that religion held over the people. Even in one of the quotes that you put up it mentions that they were not at odds with a god but with organized religion. This does not speak to atheism, it speaks to power hungry people wanting to be the one true source of information. You can find countless examples of this in history from the point of view of specific religions also, but in their case they just say all other religions, instead of all religions.
People have to take responsibility for themselves and cultivate their own, and their communities own sense of innate personal ethics. Religion has bastardized ethics and non-religious have bastardized ethics. That's why it's imperative to not base your morals or ethics on a group doctrine, but upon something more difficult to define, what's inherently good or bad. I choose not to steal not because I would end up in hell or because some organization says I should not steal, but because, through good parenting and ethical people around me, I have grown up empathetic to how it feels to have something stolen, and I would not want to cause that type of distress. The more we move away from religion the more people need to have their own sense of purpose and morals."
