I think you're not exactly understanding the story right, but maybe it is the way I'm telling it. He never said that Koeans didn't teach those flashy high kicks, but at the same time, he asked,why does it seem that people in the US who only does Taekwondo only kick hihg and yes actually Taekwondo does teach alot of groin strikes. Yes, the Korean demo team does show off alot of fancy high kicks, but at the same token I've seen them show of alot of techniques that are meant to hit low and a demo is just that a demonstration. At the same token my friend also think that one of the reasons many schools only teach high kicks is, because of how things such as demontrations and movies tend to only show off high kicks, when in fact there are many kicks aimed at the legs in Taekwondo that aren't utilized. Again there are alot of techniques in Taekwondo that are indeed aimed at the groin so I guess in Korea the do teach to hit the balls. Of course I could have misinterpreted what he said since he does have a heavy accent. Any ways I just thought the story was funny.
