I partially agree. I think anyone that trains in any traditional martial arts school has experienced that at some point. The problem is that there are concepts which traditional martial arts occasionally teach as opposed to sparring that confuse people who don't train in anything traditional, and those people try to connect the dots with a school/instructor that's a flat out fraud to something they think looks silly just out of sheer ignorance. Yes there are schools and teachers that are complete frauds, yes they should get called out because they're endangering people's lives, but should you do it? Should you call them a McDojo? Honestly, if you don't know for sure it's better to just shut up. Otherwise, do the proper research with an open mind.
