Why is that the case, Terry? Can not a western grandmaster have equal (if not more) knowledge of TKD to share with his students? Certainly, the cultural missteps are gone if your root teacher shares the same background you do.
There are many TKD and TSD organizations that are headed by Americans. Are they any for the worse because they don't have a Korean at the top of the food chain?
Yes and we have some great ones like GM Kurban, GM Pelligini, GM Sells just to mention a few, in that case threw me in the mix since I have been doing this for Twenty five years. And I'm certainly an American. See the above post for reference.
