I'll take a swing at the OP's post. I think he is talking about the arrogant, macho instructors many of us have worked out with. Their passion is not in teaching and passing down knowledge but about feeding their ego, and maybe their pockets. That said, I have seen some really physically gifted MA who just did not have the ability to teach but, thinking they did open their own dojo/Dojang. I feel bad for the arts as they are too quickly going to the wayside in lieu of the "I want it now" generation. I often say Martial Art should be Maturation Art as they go hand in hand.
