That is why I only view 'rank' as an indicator of where a student is in a curriculum. Learn to crawl before you can walk....and so on. If someone is investing more importance than that to the rank....that is their problem - OR if someone is assuming that 'you think your bad because you are an xyz belt...' that is their problem.
"ranking" within your own system is an instructor's concern ONLY so that he/she knows what to teach next and to evaluate where the student is in the overall system.
The assocations, organziation/affiliation issues are business/political and really don't have any impact on what happens on the floor IMO. But, to assume that those that are affiliated are automatically bad at their art is not a good way to operate JUST like assuming that they have to be good because of all those titles and such is not a good way to operate. Meet the people, watch their students move and interact and that will tell you volumes about their art, their character and their quality as human beings.
