These discussions can get pretty rank, can't they...
This is thread is one of the reasons I like these boards... it made me think a bit deeper and refine my own thoughts / beliefs on this subject. Thats the whole point of participating here, right?
I have always been in the camp of "rank only means something to the school that awarded it and the organization to which the school belongs." Outside of that, it means nothing. However, the questions about consistency that were raised in this thread, made me rethink a bit. Rank does have a meaning.
For me the issue is one of context. As an individual martial artist, rank only means something to the school that awarded it and the organization to which the school belongs. This has not changed. But, there is another context. The school and organization. When a school awards a black belt, they are announcing to everyone, their standards. Whether they are awarding a kid or an adult, the school and organization are defining what their standards are. They may publish whatever standard they want, but their black belts will actually show everyone what the standard truly is.
People with no martial arts have one set of expectations. When they see a black belt from an organization, they will make up their mind whether that is good or bad and most importantly, whether they want to give their money to train or send their kids. Martial artists will look at that standard as well... we each make our own judgments about the standards we see in the other schools.
I don't think this changes much, for the individual martial artist. Rank still means nothing outside your school. But, if you are ever in a position, to award or recommend someone for black belt, it would be good to consider that your school, organization and art will be judged by people watching that black belt. It may or may not be right, but it is how the world works. When you award a black belt, your are saying something to everyone who comes in contact with this person, whether they study or not. Maybe we should consider what we are saying.
