If you read his books, it’s obvious he’s doing that on purpose in order to get more attention (which eventually is converted to fatter bottom line for him).
Eh... He's always had... peculiar ideas. It's just that previously his detachment from reality was mostly in relatively harmless directions ("The Secret" type stuff, lack of belief in gravity, etc). I would buy that his current delusions might be genuine.
Are you implying that makes it better? Because I couldn't disagree more. It's one thing if someone just holds different political opinions, it's another to see problems in the world, acknowledge their cause, and fan the flames anyway. Things like posting that Republicans are likely to be hunted [1] if Biden wins are the sort of thing that led to a literal coup attempt.
