Its a moderated debate. Well, "debate" like the presidential debates where the speakers respond to questions from the moderator. The key difference is the moderator actually listens to what the speakers say and asks tosses follow up questions to other speakers, generally to the one who dissents with the statement from which the moderate makes the question. Very cool but not as passionate as I'd prefer - at least the two I've listened to so far.
But it is intelligent and very interesting. You should listen to it.
