I think there is some short thoughts here The idea that an opinion outside of the Bujinkan is wrong due to not feeling the totality of the Kan is silly. Not everything works for everyone. I for one have seen some things in the Kan that totally disgust me from some of the most senior people. Everyones needs are different, there may be less people with real talent where he is to learn from. He may just think the Kan sucks, thats his opinion. Does it look like he has moved on and has adjusted his thought due to the opposite value of what seems to be MMA, yes. Do I think that most people don't unravel the value of Ninjutsu til they have been at it a very very long time yes, do I think that you have experienced totality at a decade not too many. I think there are way too many people that think very much of their ability way too soon. That is a very obvious point if you travel enough and see the quality of the product that is out there. I do for one believe you need to see what you need to see. If that means going out for your views so be it.
