Any religion will, at some point, require a follower to stop thinking and accept that something is true just because it has been spoken by a particular person or written on some arbitrary piece of paper. Our ability to ask skeptical questions is what enables us to have and preserve freedom; give up on asking questions and the people who 'have the answers' will grab power (look up Pythagoras and his followers). That is what makes religion in general dangerous in my opinion. I have nothing against specific religious people (some of my friends are deeply religious), provided that they leave me alone.
