With the explosive popularity of martial arts, the supply of so called masters has also increased. When demand increases, the supply will always increase to meet the demand. People will do whatever it takes to make a profit, even if it means peddling fakes as the legitimate product. Martial arts is no different.
Over the years, general martial arts has become less about actual practicality but more about confidence (delusion) and showmanship with their flashy moves and screaming. This is all due to these fake masters which are nothing more than cons. A great example would be the fat out of shape self proclaimed martial arts masters. When you don’t look like you exercise at all, it just looks bad.
