I will only say one thing. You can throw all the religion in that you care to. The one thing you are neglecting is the idea beyond a particular belief, that is the world peace issue. Can one put aside the religion for just a minute to say, HEY , I WISH THIS WHOLE ENTIRE PLANET WOULD STOP KILLING EACHOTHER FOR NO JUSTIFIABLE AND DECENT REASON!
Is it too hard to give in to what would be mutually cool for all? Is it better for death and destruction? Curiously.
