I've been reading in Harry Cook's Shotokan Karate, A Precise History. There is a point made in the book that the Okinawan people, in general, were a nice, polite society as a whole, and followed the Confucian beliefs that I think came from their contact with the Chinese. So.... ...I don't really think that all of the moral/ethical underpinnings that came out of Okinawan-based styles have anything to really do with the practice of the style itself, but more to do with the culture of the people. When you take something into a different culture, I think things start to take on characteristics of the culture that they are in. Just a thought...
