His answer, as you can see, is "This is confusing" (Befuddled Old Man) and "I think you're wrong." Befuddled Old Man is the Jabba character that comes out on stage to make excuses for not understanding simple concepts that wreck his proof. Obviously everyone else understands them. But if his goal is to stall the debate, he just keeps making excuses for why he don't understand them. And he insists that we have to keep going around in circles until Befuddled Old Man finally gets it. Which, of course, never happens. Befuddled Old Man is the sort of endearing character you'd forgive for not being able to wrap his mind around an idea. He's kindly, so you don't feel right telling him he needs to step up his game.
And then, of course, the nature of a debate is to prove an opponent is wrong, not just to repeat ad nauseam that one thinks he is. That's where we are on Day One of any debate. "I think you're wrong, and I'm going to try to prove it." Now four or five years hence we're still at "I think you're wrong," but nothing approaching a valid proof has been offered. Restating the belief then just becomes a taunt.
