Wot Jack said. While I have no truck whatsoever with religion of any kind, I think that religion has been extensively used as an excuse to wage war, when the actual motive for so doing was very different. Nothing like claiming that you have God on your side and charging into battle under a crucifix, of course, no matter how unchristian your true motives. For balance, of course, the same thing happens in Islam, Judaism and, well, you name it. Some quite nasty stuff going on between Hindus and Muslims in India at the moment. Of course, religion causes huge misery the world over, generally by controlling people with an authoritarian iron fist. Religion may not kill you but it can condemn you to restrictions on your freedom, poverty, ill-health and unwanted pregnancies. And all predicated on a myth.
