I linked to a competitor in the traditional branch. I trained in a traditional branch. It is still wildly unrealistic sparring and 100% of the students have no concept of how vulnerable they are to getting punched in the face.
The freakin freeze shot is the Karateka
Punching a TKD champion with his hands completely down in a punching range. It's embarrassing how low their comprehension is for punching.
I understood it from the get go, for whatever reason... Maybe it's an IQ thing.. Who knows.
Yes, "a" traditional branch. ITF is a branch of TKD that developed AFTER my "branch." They don't practice the oldest formsets the Koreans practiced in the earliest days of Kong Soo Do/Tang Soo Do. The only reason, I wear the moniker of TKD is that my heritage supported the unification process for a time, adopted the name TKD, then dropped their support after the fall of the KTA.
As others have said, TKD is a widespread art, with many branches. Curriculums vary quite a bit, just as curriculums within Karate vary quite a bit. You won't see anyone in our dojang sparring with their guard down. We use hand techniques regularly in sparring.
I don't think anyone is arguing your experience, or really even the validity of your statements on the video you posted. Merely that not every TKD branch or school falls prey to these deficits in training or curriculum.
I have many friends in ITF schools. Some train in this manner, others do not. So even within the same "style" of TKD, things may vary quite a bit.
