We certainly agree with some stuff. We agree that the martial arts is good and that it shouldn't matter if we do different arts. We both know that all arts are different, we both know that all dojos are different (although Im not sure about everybody on this forum knowing that, some of the people on this forum have given me the impression that they don't know that dojos are different.) And I agree they should be different.
However, when you say that belts and belt color doesn't matter all that much I would have to say that depends on what you mean by not mattering all that much. As I said before, if belt colors don't matter then why not let students wear whatever belts they want in every class? That way color wouldn't matter, it would have nothing to do with rank or skill, and the color of a student's belt would just be a fashion preference. If on the other hand you are going to have requirements for students to be allowed to wear belts of certain colors on a regular basis, then in that case color means something.
I would also like to add that other people on this forum, Im not talking about myself in particular but other people who post here, based on what they post, would disagree with you that color doesn't matter much.
Anyway I've said this in other threads that if you say that belt color doesn't matter, and yet you have requirements for students being allowed to wear certain colors, particularly if you have very high requirements, you're contradicting yourself.
