I've only seen TKD in Youtube videos, and from what I saw, TKD doesn't use much defense. I've only seen it in tournaments though(Youtube not real life). But, I've read some comments say that TKD as a sport doesn't show the real TKD. Anyway, it seems that other I can learn Okinawan, TKD, or Muay Thai. When I think that TKD mostly uses kicks and doesn't have much for defense, I think that I won't have much use for it, especially in places that are too small and can't perform a spinning kick in. So, is it like in the TKD sport? or is there more to TKD when used as self-defense?
