What does measuring the effectiveness of a martial artist have to do with disrespecting them?
I think this question is key. I think that many folks have a hard time separating their identity and self worth from a critique of their action. And it's certainly not only in martial arts. Training to be a therapist, I had to go through hours of my teachers and colleagues observing via closed circuit TV my therapy sessions and tearing my technique apart and telling me where I sucked. Horrible! I first felt attacked on a personal level. At first I felt
like they were tearing me
apart, and I had to get over it if I wanted to take advantage of, and learn from the experience. I grew to welcome this kind of training.
