It is interesting to me that you say the Japanese have faith in their system. Generally in the US we dont. Many view the government and law enforcement as the enemy. I think the concept of violence anxiety is a symptom of the bigger issue of self reliance. In the west we have the pressures of being self reliant, somthing I believe is not prevalent in Japan. Being self reliant means the responsibility of self preservation and self protection falls on the individual. In the US we see ourselves as individuals, I think ( let me know if I am incorrect) in Japan they see themselves as part of a group. Is it possible that group identity is stronger than individual identity? This could make a big difference on how martial arts manifests itself in different cultures.
