Re: Pro's and con's of asking questions.
I agree. The Shihan I met decades ago had poor English, and would have been frustrated or embarrassed to give an extended lecture in English. They compensated as best they could visually and kinestheticly. Now easy to find a teacher who speaks English, but if they teach as they learned, they'll keep their mouth closed.
Angry White Pajamas, the author had to have a "teaching" portion on his test. I have not seen that in any testing in three different associations. Aside from a few, I think we are taught to imitate not educate.
