Hunkalove, first of all as I mentioned before there's no agreement on what "religion" even means. Second I'd like to know where you got those statistics regarding Hitler and Stalin. Thirdly, people have been killing each other with every justification imaginable since the world began. Sometimes it's belief in a god or gods or karma, sometimes it's an ideology, sometimes it's "keeping the world safe". And finally, there are so many people whose faith motivates them to work for peace, to live lives of kindness and generosity. However you define religion, and much as I disagree with and even fear many things that are called that, I think the world would be poorer without it.
