As for his personal life:
a. I doubt many of us know him personally; we know only what we read or hear. I know I have been misquoted in print, and a video-taped interview edited not to my liking. And I am not even famous. I believe about a person what I personally know, from actual interaction and observation.
b. As I've posted before, I think a sensei's personal life is just that, personal, and unless he involves me in it, none of my business (providing he is not breaking any laws). If I find out something I don't like, and don't like it enough, I can always leave his dojo. Senseis are not priests or therapists, and at most role models only in the children's classes.
