Given that, in the US, at least until his recent and unfortunately early demise, our most prominent Atheist was Christopher Hitchens, who had been on the talk show circuit for years, and was much more entertaining than Richard Dawkins.

Well yes, I said that Dawkins was the most famous atheist. I'd wager (in the safe knowledge that my poll will never be conducted) that if you asked a large number of people who the most famous atheist is they would not say Hitchens or that other bloke on yank telly that somebody mentioned who I'd never heard of. Not only that, you dispute my most famous atheist by replacing him with an apple-and-pear most prominent atheist. We have different words for things like famous and prominent because they mean different things, old chap. Frankly, I don't give a flying shite, but it is still highly amusing to note your unequivocal assertion - no room for cavils here! - that Given that...our most prominent Atheist was ( not probably was, etc.) Christopher Hitchens... So who's being indisputable now?
