I agree that there will always be some charlatanry in martial arts. It seems like it’s an inseparable part of combat itself. The dude that conquers foes through fear, even if via deception, has expended zero extra resources. I was a huge Bruce Lee fan in grade school. I didn’t have any sense of which part of his art was for show or for whooping ass, but man did I walk taller after seeing Bruce lay the smack down a platoon of henchmen. Real, or just facade, there’s always going to be folks that flock to perceived badasses. As I type this, I think I’m getting at the core of the popularity of Donald Trump.Of course, the problem of charlatanry in martial arts remains an issue (and I don't accept the sadly-common belief that UFC is the ultimate arbiter of this), but that's always been the case and always will be.
