Currently Steven Seagal is getting raked over the coals on Reddit due to some of the extraordinary claims he's made about his martial arts abilities, they don't quite line up to our current understanding of what is effective (think, less Aikido and more Ju-Jitsu, at least in the ring).
I think what has happened to Steven Seagal (and here to Jim Cramer) is that we're now in the era where it's possible to (somewhat) easily fact check the claims that you make and prove that they're wrong.
