I think this discussion applies not only to taekwondo, but to sport martial arts in general:
- Boxing is not really very much like a real-world fist-fight
- Wrestling (Greco-Roman, Sumo, Ssireum, etc.) is not very much like real-world grappling
- Fencing is not very much like a real-world sword fight
- Sport archery is not very much like bow-hunting
- Target-shooting is not very much like a real-word gunfight
