With all due respect to the parties in question, the first thing I would recommend is purge your mind of the propaganda. I know of your instructor and the group he of which he used to be a member. They're all pretty bitter and very much closed minded. They also pass down a poor attitude to all of the students that I have interacted with and tend to be pretty insular, thereby propagating the legend they have created. My advice is avoid any system that holds grudges or ignore it as long as possible. There are issues with any MA group, even mine. I ignore it and go on. Also, contact people associated with the style and start getting outside info and reach your own conclusions. Also, remember that your instructor left his MS sensei as a shodan. He's not teaching you more because he left at a time where he only had hold on the basics. The real work begins at shodan. The best weapon in martial arts is an open mind...
