No, he's not a decent debater. Here are his moves:
- Talk over someone, get pissy when he gets interrupted. Be a bit condescending sometimes
- Jump from "fact" to "fact" too quickly for anyone to follow, and when someone takes issue with a "fact", call their credentials into question so the "fact" stands
- Always answer a direct question with something that is not a direct answer
He just doesn't have a pause in between using these while presenting confidence, so it seems that he knows what he's talking about on a superficial level
