How can I tell if a martial arts school is legitimate or a McDojo?

This is really an issue and thoughts that makes full, wide and long debates on some people involve in Martial Arts, because being legitimate has wide meaning in it and interpretation varied a wide definition, every person insist what he thinks is right behind his minds, especially if those people had been corrupted by the wrong teachings about legitimacy of arts that rises on certain place. But for me, if one style been occur on one place bringing the name of certain arts, it is hard to say about its legality, unless a person will check the instructors background and the origin of his skills and knowledge, judging them is like you are saying that such is the content of the books by just reading his cover. What matter most here is the know how of the instructor and he followed the curriculum of the style the taught, he knows what to do, what to give and what to instruct.

This is the hard point on this recent forms of Martial Arts, once you are not involve or not a member under their organization, then you will feel the discrimination point of being out in the line, they will not consider you a legitimate instructor, a side scenario because most existed organization now are relying on the contribution and support you can give to them. Being legitimate, wow, so funny but things are really hard to know if how some people consider this.

Legitimacy applies to what an instructor is teaching in relation to the style's founders. If s/he's teaching close to the original style, then, it's legit. If not, then not legit.

Either way, it's still a martial art. If what s/he's teaching isn't legit, it doesn't mean it's not quality. It just means it's not being taught according to the philosophy of the founder(s).

Legitimacy can apply to a style "as a martial art". Haymaker Fu is a method of self-defense, but it's not a legitimate martial art. There is no stated philosophy, and it's not battlefield tested.

Legitimacy can also apply to the quality of instruction. An instructor may be teaching a legitimate style, but if s/he's a crappy instructor, s/he's not legitimate. Similarly, someone who reads a book "SumFlungDung Do for Dummies" may be learning ABOUT a legitimate martial art, but is not legitimately learning it (and depending on the author's credentials, may not even be learning a legitimate martial art either!).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
