Hi Draug, OK, thanks. I didn't say Christians were more so any of these things, only that they were no better than atheists. It seems we are in agreement on this so there's really no reason for me to have provided citation anyways, right?
@Semck, I didn't read it in depth, just skimmed. The journal is peer reviewed and is written by somebody with a modest background in the area, hence my, "looks legit." Your claim that failing to control for various other potential factors may be legitimate to some degree, and it is true that correlation does not equal causation. I accept at face value that economic concerns may very well be the true cause of both religiosity and infant mortality in many countries, for example.
I don't feel inclined to press the issue further, since I personally am not actually claiming that religiosity makes people more violent. I only that say that claims that religiosity makes people less violent are unfounded - so if you can accept that claim we can let it lie at that.
