Friends, I'm not saying your comments aren't worthy of discussion, but after all this thread is titled:
"ATHEISTS who have committed mass murders and genocide in the 20th century".
Show your fellow atheists (Stalin, Mussolini, Pol Pot, et al) some respect here and discuss their noble humanitarian reigns and deeds. If I wanted to discuss THEISTS who have committed mass murders, well, that subject just seems to be a little over-done on this forum, but we can start a new thread and get totally redundant, reposting old posts and saying the same stuff that's been said many, many times in this forum and pretending its all new.
I don't have a problem discussing theists who have committed mass murders and genocide, because I acknowledge that there are theistic leaders who have done so. I also acknowledge that just because someone claims to be a theist doesn't make them one, but I also acknowledge that just because someone claims to be a theist doesn't make him any different in my book from an atheist. Theism in itself is not noble or grand. It can be just as hideous, or more so, than atheism in my eyes. Belief in a god or gods doesn't mean someone is morally superior to someone who is an agnostic or an atheist.
