I want to say the big reason behind this is when people get there 2nd or 3rd dans they like to go "independent" from their original teacher...being independent and not "subordinate" to a Master in an organization are the waves and democracy of the future...we can accept this or become a part of the minority which won't be well respected by the rest!?
I also find that people in this industry who "criticize too much" the issue about credentials ( notice I only criticize the black belt home study courses and rank testing), these people are simply trying to give validity to their own rank for one reason or another.
I don't think this applies to you, you seem like you have a good thing going down south however you still seem to have a hard lined stance and I am not sure if its based upon ignorance in the industry, maybe you haven't traveled around the country and met 1000s of Martial Artist including many in your own style? I am very confident about my rank and what I have accomplished; I am well respected in my part of the country and know my ranks are well respected in many other parts of the world including Asian countries. I am not offended by your opinions I just find them amusing. However, others especially in your Art of TKD might get offended by some of the things you say.
