I wonder sometimes, if there was no religion, would the hairless apes of Planet Earth simply latch onto some other ideal or philosophy that they would be willing to kill for? Someone once told me that faith was the culprit in clashes like this one rather than belief in a god or a religion.
Faith can be placed in anything I suppose, whether it is a person, place, thing, idea, or philosophy. However, it seems to me that those who consider faith a moral virtue also attach the qualifier that it's only virtuous if it is in agreement with their own values. As long as the hairless apes on this planet hold to this way of thinking, I doubt seriously that any peace we might enjoy would ever last longer than a fleeting instant in our brief, tumultuous time here.
