and I have been corresponding for the last few years, and I have no reason whatsoever to doubt what he wrote there. In fact, I've heard quite a bit more off-forum about this group. Enough to convince me that regardless of how physically skilled they are, I would never set foot in their dojo. True budo should improve the whole person, and if someone who has supposedly 'mastered' an art still finds it in themselves to lie about what they do and hold unhealthy sway in their students lives, they, in my view, have failed as budoka.
