I agree with you. The concept of using analogies is always good in whatever profession, and the idea as a teaching tool certainly did not originate with the carpenter. There are several philosophers/thinkers throughout history who did so.
As had been said in another thread on Part I of this same subject, I agree that Mr. Parker is a Kenpoist who happened to be LDS. He could just as easily have met with Mr. Chow elsewhere and had the same conversation. Had Mr. Parker been of any other faith, I believe Mr. Parker would probably still have an interest with the martial arts, and continued to become the "Father of American Kenpo".
Basically, I think it is generally a waste of time (although an interesting mental exercise for some) to wonder what would have happened if a certain circumstance/background was different.
