When someone claims they are a grandmaster in chess, and then talks about how the king is important ("you can tell because it's very tall")... and doesn't know how the rook moves, then yeah, if you never heard of chess, and can't be bothered to learn why that is so terribly telling, then you can indeed say nothing to that. > Most people who surmount incredible odds aren’t normal, stable people so I don’t know what your point is. The issue isn't "not being normal", that's not just moving the goal posts, that's throwing them away and saying "I don't see the problem". Fine, so you don't see it. Doesn't make it go away. I asked for one thing you have evidence for him doing that you personally have expertise on. That's not "documented in the book", because you are not mentioned in the book.
