The other day I wrote something to upset the followers of Richard Dawkins and one of them tracked me down to a pub. I had been asked to give a talk to a group of ‘Skeptics in the Pub’ about whether there are any atheist babies — clearly not, in any interesting sense — and at the end a bearded bloke, bulging in a white T-shirt, asked very angrily where Dawkins had said there were any.
