I would have to say that faith and spiritualism aren't necessarly a bad or a good thing. It depends on the context, just like everything else. I know people that are spiritual, and it's a good thing for them. It improves their sense of hope, gives them something to look forward to when they are going through a miserable time in their lives. They use it as a tool to guide them through life. On the other hand, I've met people that act completely brainwashed by their spiritualism. They except whatever they are told by their church with the attitude that evolution and non spiritual thinking is completely wrong and for no other reason then they were told it was false,etc. So basically, good and bad things can come from faith, spiritualism, religion etc. The topic is too broad to correctly debate. A narrower aspect would be better to review.
And now that I read through the posts again, I realize that we aren't talking about faith and spirituality, but about creationism. My bad, oops. Disregard my former post. I agree that creationism is a bad thing. People believing in an idea that can be completely disproven (especially since people believe in it in such great numbers) by science is completely horrible.
