I'm not sure how that changes the fact that everything he says is either completely untrue or irrelevant. If you want to point out an inaccuracy in what I've said, feel free.
I don't see how you have enough information to make that determination. It's a presentation deck. Those are just bullet points, not the arguments you would (presumably) hear in the full presentation.
Could you give one example of an argument made in the deck which has been "thoroughly debunked"?
Most of the things he says are actually false arguments that no one is trying to make or just completely irrelevant.
