Thats enough for me. I don't care what ideology they wanted in their "perfect society". Just imagine, handful of athiests with perverted ideologies are worse than the billions of religious people who follow their religion.
Why would anyone want more atheists?????
You're making an enormous mistake and you have been throughout this whole thread.
I'll keep it simple and quick and if you'd like, we can go from there; though there'll be really nothing more to say.
1: Even if they were atheists, killing in the name of atheism is no different than killing in the name of being tall/tallness. Why? Because despite sounding silly the key point here is that there is no motivator other than difference.
An tall killing the short (Or extremely tall) has no motivating factor other than because the target is different.
This is why religions actually can be held much more responsible for when an atrocious act is committed in it's name, because they do supply very strong motivators. An obvious example is looking at the Islamic suicide bombers.
Atheists killing someone else will have a reason, not motivated by atheism. An example of this would be Stalin himself who largely did so for political reasons such as ridding his system of competition for his own ego.
2: Now in your statistics you're also forgetting the fact that these dictators lived in a technological era were mass killings could quickly be done. Considering the large numbers religions have managed to murder during their own times there would undoubtedly be a much larger percentage of killing done in the name of religion.
There's also the fact that a large number of deaths religion is responsible for isn't even considered as it's not an active persecution. One such example is the still continuing HIV crises in Africa due to the Catholic church's fantastic resistance to permitting the avocation of condoms leading to the death of countless people. All because they think putting a piece of plastic on their genitals will offend a zombie-wizard in the sky.
3: Last is the fact that outside of these specific figures, what atheists in everyday life- say in the US - are like these terrible people? The last time I checked it was an abortion clinic that was bombed, not a church. Although, there was an attempted bombing of a synagogue that was apparently prevented recently, but these individuals happened to be religious as well so that really doesn't help your case.
4: You're making a fallacy - sweeping generalization. Again, you're taking a few examples and then using it to brand all others. It's disgusting and highly offensive as well as extremely ignorant.
