Good discussion. If we look at the state of affairs in the United States, we can say with certainty that ITF Taekwon-do is mostly fractured. Competition is good and it makes everyone lift their level. But that requires cross pollination. Everyone should be open to learning at all times, and that includes from other groups. Particularly when those groups are from the same tree roots. Operating out of fear, usually does not end in larger more cohesive groups. The question of loyalty should not come from a place of fear. You can be loyal to your instructor and support other ITF organizations.
