Let me ask you this--why did all of the major atrocities of the 20th Century occur in atheist/neopagan nations, and why did the Christian nations of the world champion life and freedom?
It's the same reason America has a Special Olympics and China doesn't. Christian respect for life. Children with Down's syndrome never make it out of the delivery room in China. That's atheism in a nutshell.
You continue to ignore the points I made: (1) non-atheists can kill on a grand scale; and (2) non-atheists can be communists. Now that we've established that you're still ducking, and still living in a fantasy world where: (a) atheism = communism; and (b) theism = virtually no murder and no communism, let's get on with one of your points (I'm free to ignore any of your other points, as you are free to ignore mine).
In the 20th century, Germany in both world wars was a Christian nation. They did not champion life and freedom. Okay? Your worldview still hanging in there? I figured that. Keep ducking, it's the only way you can cling to your fantasies.
