I think humans as a species will go to war with or without religion.We are just tribal animals like chimps but more evolved.Chimps are nasty bastards.If they see another chimp from another tribe out alone they will stamp on it and rip it's bollocks off.Seriously.
Religion is just an excuse for war.
The thing is.Most religions have evolved into a peaceful state.Islam is still young and is still fairly primitive and it's not a giant leap from its 'moderate' form to the Jihad embracing extreme form.
