Let's be fair. There's any number of examples of atricities, torture, genocide, etc. that can be attributed to deists in general and specifically christians. There's nothing inherent to communism or china that makes people particularly cruel. If anything it's a persistent part of the human condition and has nothing to do with politics. We all like to look around and ascribe blame and horrifying events to systems, people, cultures we understand the least. But if we look hard enough we can usually find similar examples perpetrated by people with largely the same beliefs we have and who look just like us. Plenty of monsters who ascribe to democracy and christianity. Plenty of saints in China. We're not all that different. Atheism (not that there aren't millions upon millions of christians, muslims, buddhists, taoists, etc. in China) really doesn't have anything to do with it. I'm an agnostic and I won't even use a mousetrap in my house. Besides, state views on religion don't really have much to do with the thoughts of the populace on spirituality. Communism didn't remove belief in god from millions of russians, it merely made it harder to practice openly. Same thing in China.
