Good points, Tigerrr.
Thinking back to other debates of his that I saw, he made Tony Blair look pretty silly, I thought, when they debated religion ("not difficult" I hear you cry). The more I think about it, in the Iraq War debate with Galloway, I always felt that Hitchens was bound to lose because he had "backed a loser": it was as though he couldn't find it within himself to side with a majority. If he had, for example, decided to take an anti-war stance, who would have taken him on in debate? Galloway is a pretty sharp debater but I watched that debate from start to finish and thought it was quite one-sided, especialy for someone with Hitchens' reputation.
I suppose I'm speculating that he "threw a fight".
