Will gormless be terribly upset to learn that Dawkins (and indeed every athiest I know) is very well aware that God's non-existance cannot be proven and is cited in TGD? Bertrand Russell formulated perhaps the best-known response to issue in 1953 with his celestial teapot.
As for the accusations of bile and spite and anger, Dawkins is passionate certainly but one only has to listen to the man (gormless obviously hasn't) to know how measured and calm he tends to be. He's also dryly amusing.
A friend, an intelligent lapsed Jew who observes the Sabbath for reasons of cultural solidarity, describes himself as a Tooth Fairy Agnostic. He will not call himself an atheist because it is in principle impossible to prove a negative. But "agnostic" on its own might suggest that he though God's existence or non-existence equally likely. In fact, though strictly agnostic about god, he considers God's existence no more probable than the Tooth Fairy's.
Bertrand Russell used a hypothetical teapot in orbit about Mars for the same didactic purpose. You have to be agnostic about the teapot, but that doesn't mean you treat the likelihood of its existence as being on all fours with its non-existence.
The list of things about which we strictly have to be agnostic doesn't stop at tooth fairies and celestial teapots. It is infinite. If you want to believe in a particular one of them -- teapots, unicorns, or tooth fairies, Thor or Yahweh -- the onus is on you to say why you believe in it. The onus is not on the rest of us to say why we do not. We who are atheists are also a-fairyists, a-teapotists, and a-unicornists, but we don't' have to bother saying so."
