Does reason have enemies?

After watching the videos on Richard Dawkins (including the one with Bill O'Reilly), can you say that reason has enemies? Can atheists be angry like religious fundamentalists? What is wrong with believing in a God, in the stars, in pseudo-science, in superstition, in magic, etc.? Whether all of these things are wrong or right is beside the point. Can they really be harmful to man-kind?

Of course reason has enemies, reality sometimes is really hard to believe; sometimes we simply don't want to.
For some reasons, human beings need to believe everything has a meaning. We are struggling every day to find meaning to our lives. Reason is of course a way to find meaning of things, of natural phenomena, for example. What human mind can't really easily accept is that certain things happen just for a coincidence. It is something scary, because we can't have control over chance. And we want to be in control of everything. We want to see order and meaning, we are so scared of the unknown that our minds is willing to believe literally everything, from tea leaves to stones, from planet positions to people charmingly claiming to have paranormal powers. Can all these believes be harmful?
History have taught that people that have strong believes that go against reason have the tendency to impose them on others, usually in very violent ways. Dawkins, at the beginning of the video, says something very important: that we live in dangerous times when superstitions is gaining ground and rational science is under attack. That makes me think of the Medieval times, when superstitions had many fellows and the scientists were persecuted. Is this happening again? I don't think that the situation is now as bad as it was, but yes, superstions and believes can be harmful: let's just think of all the people that spend lots of money and become addicted to this "magician"  that claim to solve their problems.

But, after all, is there something that men can use without being harmful? Science can be harmful as well if used for the wrong purposes. 

In what I disagree with Dawkins is the fact that he wants to "get rid" of the superstitions. This is impossible and useless because, as I've said, humans need to have a faith and worship something. There was a South Park episode in which there was a future that, thanks to Dawkins himself (and miss garrison - by the way) was now completely atheist. The thing was that people still managed to find ways to argue and kill each other because atheism was the new faith and Dawkins the new god. 

I perfectly agree on the fact that they impoverish our culture and undermine civilisation, but humans are imperfect and all of us have our own weaknesses... For some it's chocolate, for other it's the horoscope...
