This is essentially correct. Most of the old school Chinese kung fu Sifu's (Includes Chinese born, American born, European born etc) have an attitude problem in my opinion.
This all stems from the Chinese culture of pride, pettiness and losing face. My wife is Asian and I see this attitude in her as well. I have noticed over the years that many old school Sifu would not associate with other Sifu or if you did not play by their rules, they took their ball and went home.
All of these old school attitudes hinder CMA. Modern people are not quite as bad but, people like Nick are part of this old school regime.
