How is it apparent that Dr. Yon was held "in very high esteem by many Japanese seniors and contemporaries"? Where does that come from? I would say it is a big deal for you, since you mention it so often. You mean this page in this history section? http://taekwondojidokwan.com/ If so, then you learned about it recently. And it doesn't mention any "schism" in the article. However, the Chosun Yun Moo Kwan/Jidokwan section from the Modern History book immediately follows the GM LEE Chong Woo interview. Perhaps you were reading that and misunderstood that to be GM Lee's interview. But funny how you once again cite to a Korean source for information, instead of a non-Korean one, which you claim is less apt to be "biased".
