I've seen many a simpleton opine that religion is the single greatest cause of war. This is simply not true. Religion is however, one of history's most successful tools for unifying a populace and maintaining public order. And yes, this very element has oft been exploited by leaders of men as a means to arrouse support and justifcation for going to war. But that makes evil those that exploit the tool for evil, not the tool itself. If a man hacked up your family with a hatchet, would you blame the hatchet or the man? On the whole, religion has been an absolute boon for humanity in terms of both survival and prosperity. Without which we may very well not be here talking about it today. To categorically dismiss religion as a scourge of humanity is to betray a marked dearth of wisdom and maturity.
