It's a matter of degree. Lets say we assign percentages and then provide evidence. Okinawan, Japanese, Korean, Chinese how much of TSD draws from these areas? Lets not look at the origination of other arts because then we are just going to get back to China. Lets limit this to the cultural contribitions from the time of the founding until the present.
One thing I'd like to tease out is exactly how much and where the Korean influence is evident in TSD.
Is it fair to label Tang Soo Do as "Korean Karate"?
