On another thread dealing with McDojos and dubious quality instruction, MJS posted that it raised a "red flag" when an instructor claimed very high ranks in multiple arts. Now, there are dedicated individuals that have legitemately achieved high ranks in two or three martial arts. And there are also high level masters who, because of their skill and experience, have been able to adapt useful skills from other styles without devoting the many years it would take to become a "master" of each system. But, on the whole, I have to agree with MJS's comment. When I pass the neighborhood "McDojo" and see signs advertising instruction in "Karate, Kung-fu, Kenpo, Taekwondo, Kickboxing, Muay Tai, MMA and Ninjutsu", I don't know if I should laugh or be ill. And I feel the same way when someone starts claiming 6th, 7th and 8th dans in five different systems. I suppose there may be a few such individuals out there, but they can't be common. What do the rest of you think?
