That is how it usually starts, an interest in olympic style competition. Many ITF converts have done very successfully in WTF competition. GM John Holloway from the US was a bronze medalist at the first ITF World Championships, and then became a multi time medalist at the WTF World Championships. In fact, many in the USTU had ITF backgrounds, including one president, GM Holloway's instructor, Dr. YANG Dong Ja.
The ITF instructors that we helped here back in the 90s, they still have a fondness for the ITF forms, which frankly I never understood. But they teach the taeguek and yudanja poomsae to their students, but still practice their itf forms on their own. Welcome to the family.
In Hawaii, we have this concept called ohana, which means family or extended family. Some strict constructionists say that ohana means only blood family, but most people here apply it to the extended family. People welcome you into their homes and make you feel part of the family. I believe that this concept extends beyond Hawaii and is also part of Korean culture as well.
But I also realize that many come from dysfunctional family situations, which may also extend towards their martial arts teachers. They were abused, or mistreated, in their homes or in their martial arts schools, at least in their minds, and now they project that to everything and everyone. As a fellow martial artist, I don't think I or anyone else can do much for these types of practitioners, who harbor hatred and resentment and anger toward their teachers, or their art, or those that created their art. I think that type of attitude, the smoldering negativity that is just waiting to be released like a volcanic explosion, tends to affect their entire martial arts experience. Luckily, that type of negativity is not as contagious as it once was. That type of phenomenon ran its course over the last ten years. But there are a few who still carry the chaotic banner of death and destruction for anything kukkiwon, wtf, or usat related. Those people, we cannot help. Today, people look at that type of irrational hate filled, ranting and raving and go "Whoa, that's not where I want to be."
But luckily for every person like that, it has been my experience that there are a hundred more out there who are sincere, who do wish to be a part of kukki taekwondo. For those, there is many things we can do to assist them. UK is a different animal, it has its own issues going on, but if you need help with Kukkiwon certification, I have a couple few friends there who can assist you.
