I like his interviews too. ;) Those are less opinion centric. He certainly has a right to his opinion.
I only heard about "Appeal to Stone" myself 6 months or so ago. That's the thing about critical thinking, you can't really master it, you can just get better at it. So it is something I really try to learn something new about a little at a time. There are tons of different logical fallacies. I think I know the most common ones, but there are some obscure ones I haven't internalized yet. Knowing them is just as important for policing ourselves as it is being able to see past the fallacies used by other people. I make mistakes. Hopefully I learn from them.
