sure it does, it qualifies you to talk about your one art, since thats the only thing you know.
in my case it isnt. Yes, your knowledge of KKW TKD is much, much deeper than mine, but I would say that my knowledge of arts "overall" is deeper than yours.
thats just opinion, and i might very well be wrong.
I say 8th degrees are honorary, because in general, across the spectrum of martial arts as a whole, it isnt based on physical skill, or developement. Even if there is a physical test, the promotion wont be based on "they are getting better" like 1st or 2nd. It is based on how many BB's they produce.
And let me say this again.
I dont give a rats rump what the KKW does. It can go away for all I care, and I would be just as happy
All i can say about that if they have a phsical test for 9th degree friggin BB? well at least then they can justify what they charge........................
