To me, all these "book" religions are barbaric and acted likewise at one time in history or another. They worship the same cruel god that treats some of his own children in the "heaven", with or without virgins and honey, and put the others to roast in fire, sends his fidels on crusades and forced conversion campaigns. Thus the never ending wars that have eradicated many peacefull peoples on this planet.
Religion and peace in the same sentence is the very definition of an oxymoron. Talk of the light of darkness.
