The Adaptive Value of Religious Ritual

I don't agree with this article at all. I think that its crazy people hurt and harm themselves because of their religion. I guess I think that cause its not my religion and I wasn't rasied in that and don't believe it but it saying nothing about physically harming yourself in the Bible. But I know everyone don't believe in the same thing so theres not much else I can say about this. Don't want to offend anyone.
