I don’t really agree with his conclusion at the end, but he does a great job of showing several sides of the situation. Personally I think that it is important to call people on things that they are not rational about. I don’t know if I take it to the level that Dawkins does, but there is something to be said with having the strength to stand out and say that you think the majority of people are being dumb.
You can have your beliefs if you want, but when you come to me talking about them, you better damn well have something to back them up besides passages from the Bible and the need for ME to prove YOU wrong. Luckly, for the most part, my ideas fit with the world around me. If you want to try to believe in something that doesn’t match the world, I think it is important for you to have some logical reason that your belief is right.
