Gee, I must be a psychic, cause I predicted exactly what you would respond to that post. You can ask what the moral utility of it is when you show that the severity or times atrocities committed are not lower because of those belief systems. How do you know the atrocities wouldn't have been far worse or occurred far more often without them, how do you prove that people that were true to their belief systems were the ones committing the atrocities? You want to make it simple when it's far from simple. I haven't 'blamed' anyone, but you're clearly blaming Christians and their faith for your litany of 'crimes', and offer no proof whatsoever that there is a correlation there at all. You'd be able to prove your arument simply by pointing to a secular socity that is free from any atrocities, and you can't.
