while it's important to criticize intellectuals on their positions, especially if they show ignorance on a topic they're debating and especially if they're tryng to position themselves as expert in the subject matter, it's a little unfair to expect them to come into life fully formed and knowledgeable about everything. as long as they're honest about it I think it's ok for debates to happen between people that aren't subject expert. how are they supposed to learn, alone in a cave?
