Do you think that TKD as a whole has a good reputation, either within or without the MA community? I can think of some TKD people here and in real life whom I am guessing run top notch programs. But they are among the people who lament the most about how commercialism, selling out for profit and inclusion in the Olympics have led to the current state of TKD in the world.
Edit to add: At some point, how you measure success or failure needs to be stated, as well. I mean, it's clear that there are many people who are perfectly happy with how TKD is going and don't see any reason to change a thing.
At some point, we have to make decisions about credibility. No one can know everything about anything. It's all different degrees of ignorance. I'm more ignorant of TKD politics and history than other people.
But in a situation like this, lay opinions are relevant. What people who aren't fans of MMA think of MMA is relevant because that speaks directly to its marketability in a venue like the Olympics. In the same way, lay opinions of TKD are relevant, ie, what effect the Olympics have had on public perception of the art of TKD.
