Collective Religious Rituals

The summary is that regular participation tends to correlate with increased likelihood of being part of some kind of extremist action. Perhaps no surprise there. However there is scant support for the neo-atheist condemnation of all religious activity: "researchers note, the greater sense of community, developed via religious services, may have many positive consequences. They observe, 'Only in particular geopolitical contexts is the parochial altruism associated with such commitments translated into something like suicide attacks.'"
Of course it serves to indicate the teaching of total depravity may have something to it; that is that there is no area of human experience which is off-limits to the effects of the fall -even, perhaps especially, religion.
