I think it's a pretty safe assumption that all the comments here about "normal non-self help guru celebrities don't get stalked as much" are from men. I think literally every woman who is even semi-moderately in the public eye has stories about stalkers, regular death threats and rape fantasies, etc.

Glad to hear other commenters are pushing back against this proposition that Ferris is somehow a special case, because it's a story I've heard from lots and lots of people in the public eye, regardless of their area of expertise.
