Is it true that atheism has killed more people then organized religion?...

[Entropist]

A lot of Christians say that atheism, particularly Stalinism, has killed more people then religious conflicts. I wouldn't yet say that I am a full-fledged atheist, but is this true? PLEASE note that this question is not meant to offend anyone on these forums; I'm just looking for the truth on this issue.

Firstly: Just because all communists are atheists, it does not follow that all atheists are communists.

Secondly: The mass killings that took place were not done "in the name of atheism." They were done in the name of a particular political ideology.

Atheism itself has nothing POSITIVE to say-- taken by itself, atheism isn't even an ideology-- it merely states a [edit!] lack of belief in any gods. One has to go BEYOND mere atheism to start making positive belief statements about the world, metaphysically, morally, scientifically, politically, and so on. And those beliefs can vary widely: Secular humanism, nihilism, existentialism, objectivism, anarchism, naturalism, and a bunch of other -isms. Atheism simply makes these other beliefs POSSIBLE for the individual. That is all.
