TKD does things differently and unfortunately, as in life, if your not in the mainstream people have issues (Just my opinion). Of course it works both ways. I read that TKD masters used the red belt below black to stick it to the Japanese/Okinawan masters. Not sure this is true because I was not there when they did that (I feel younger already! ) but that is what I read somewhere. Someone (can remember his name) studied under Toyama and his students (the guy who I can't remember his name) had students who founded some major Kwons. Look it it this way, now that I think if it I like to think of it this way, it's boils down to sybling rivalry. Again, just my opinion.
