And where did that Crusading tradition end? The IRA, the Anglican Church, the Inquisition, the Conquistadores, the Vatican, witch hunts, the churches and priests who condoned and conducted the wholesale slaughter of indigenous people on two continents, zie Germans in two world wars--just a tiny part of a very violent history, and all subscribers to a belief that killing is wrong, no matter the reason.
I'm just saying that when that conflict comes, and neighbor turns against neighbor, it'll be a religious man that hacks your childrens' hands off.
