Naturally I fully agree with jake and China, it being a truly noble thing to use reason to break the hold that mindless superstition has had on people for millennia.
But then, why should a mere, commonsense refusal to believe in a supernatural being be required to have 'done something' anyway?
What has my non-belief in Tarot Cards (crystal balls/astrology/spaghetti monsters/ palmistry/ spiritualism, etc.) done for the world?
As for Dawkins,123everton, I think you should read more of his books. You'll then learn that he is a very humane fellow with a great sense of humour and a deep love of humanity. (And why shouldn't he challenge the cruel exploitation of sick people that the RC Church practices at shrines like Lourdes?)
At any rate I reckon he's a few notches above a bloke who uses disgusting scatology to insult him.
