JF's web site does bear a lot of the hallmarks of classic crackpotism. Even the style (or lack thereof) is an indicator. I think he read that Internet article published in 1997 that said that most people consider black text on white backgrounds to be more professional and he'll be damned if he strays one bit from that bit of advice.

But the true sign is the long list of letters after his name name along with the talk about how unscientific everybody else in the world is together with the use of all the classic unscientific, emotional tactics he criticises others of doing to make his own arguments. THAT is classic crackpotism.
