Wars may begin by miscalculation and misunderstanding. Civil wars, too.
Wars of religion did not end centuries ago — our secular world is highly religious and all the more so because their faith is so great that they do not understand themselves as a people of faith. As such, we are already way down the road of miscalculation — their belief exceeds that of any snake charming fundamentalist. This is dangerous to us who proclaim Jesus Christ as Lord.
