'That said, the "oh God" thing is just silly.'
Not sure if anyone has explained why the British press jumped on this - In a discussion, Dawkins (mockingly I presume) used a survey which showed that most British 'Christians' could not even name the first book of the new testament. In response, the Archbishop (I think it was) asked Dawkins for the full title of Origin of Species - ouch! he couldn't remember it, and that's when 'oh God' came out. A double whammy.
Personally, I find Dawkins comes across as arrogant and militantly anti religion. He clearly believes that anyone who believes in God is either ignorant or stupid, and sometimes, when he's not in charm mode, he says so out loud. You can call that honest, but disrespectfully trampling on the fond beliefs of millions is bound to get him into a little trouble.
