diplomat61 - I did not say that all atheists are "free" to be murderers, rapists, etc. However, as Ursa pointed out a post or two before this one, the fundamental problem with atheism is that there is not a particularly firm ground for preferring one moral system (for instance, the rough approximation of the one we have in the West), over another. This means that while you can argue with someone about what to do and what you would like to be wrong/right, with no external reference, it is hard to justify why someone is right or wrong. For instance, I think most people agree that some of what Stalin did in Russia was brutal and wrong, but from a different perspective, he stayed in power until his natural death (though there is some dispute about that) and he made sure there was no revolt, so from his perspective and those of his close associates, he was pretty effective in keeping things the way he wanted them, so, without an external reference of right and wrong, how can you really say that what he did was wrong (i.e. how could you justify to him personally that he was wrong)? With no absolute (i.e. external) basis for morality, pretty much anything can be justified, by the right person or group of people, to be acceptable.
