Atheist ideology was directly responsible (in the guise of Communism) for hundreds of millions of deaths. From Stalin's great purges to Mao's starvation marches and everything in between.
Mao's actions were undertaken with the aim of ensuring a functioning Communist society the way Mao himself believed it. Mao did not lead "starvation" marches because people worshiped God.
Imo, if religion was taken away, it would be the destruction of human choice, and subsequently of life itself.
I also subscribe to the line of thought that if there was absolutely no religion or root thereof, the morals that people create for themselves would forever differ, and create even more conflict. To one person murder could be completely fine, and to another abhorrent, but who would then decide that?
Better allow people to choose clearly defined stances, than to create 6 billion minute ones where groups of the same ideology would subsequently form anyways.
I dislike this post. How would atheism destroy human choice? Because people would be able to decide for themselves their own moral code (in accordance with the law, and other social norms, and of course your own personal values) rather than conform with archaic ideas?
Secondly, religion needs to get off its damn high horse. Why the hell should religion- which has itself been the root cause of so many wars, tortures and other atrocities be allowed to determine what is 'right' when it can't even learn off its past mistakes. The same atrocities, such as torture, have been committed in most religious sects i'm sure. What has religion done to deserve the view that its morals are correct, unquestionable, and obviously better than anyone elses? Because I don't believe in God my morals are of less value? Ignorance at its peak if I may say so myself.
And to your final statement, consider the second part of what I wrote (in the starting post), and the definition of atheism I provided. Atheism is the desbelief of deity's, and this idea would be far more uniform between people than an omnipotent force- who has been interpreted in countless ways.
