But that is my point. Arts like Tae Kwon Do, Karate-do, Aikido etc. were designed as an overall program of physical, mental, and spiritual improvement. As such, each aspect of the art (forms, sparring, self defense etc.) were just that-aspects. Sparring or whatever is not the total package. And because these arts are grounded in tradition, either from the native country or imported by its influences, things like uniform, behavior, etiquette, and manners are spelled out. Remember, these are Ways of Life in how to better yourself.
KJKB is primarily for self defense, and has been for Day One. Either you or someone else said it yourself. Tradition, etiquette, manners, uniform etc. mean nothing. I also have a problem with that BTW. But if all you care about is self defense, if culture, etiquette, and tradition mean nothing, then you don't need rank or uniforms because all you are teaching is self defense techniques. Why do you think Jeet Kune Do doesn't use uniforms?
My opinion? KJKB is not appropriate for young children because they need something with more substance.
