This is not representative of the rest of the event. The athleticism the real competitors were doing was incredible. It's closer to an improvised, artistic version of a gymnastics floor routine than this bullshit.
This person undeservingly getting a spot on stage is not representative of the sport. But surely you wouldn't be commenting on the validity of a sport after seeing only one person do it because then you would be susceptible to being wildly misinformed
I wouldn't. Like many other sports, bboying (which I use because it a dumb AF moniker) is totally subjective for scoring, and as someone who has done a LOT of karate, gymnastics, and ballroom dance, it seems like all of those should have been included first.
It's not totally subjective, because they define a way to measure an athletes performance objectively. It's also a bit ironic because gymnastics could also be quite subjective too. Ultimately the judges and the athletes are aware of how everything is being scored, and the athletes plan their routines around how highly they can score on this rubric.
First because they are older sports. Maybe that is the problem though because karate and ballroom both have 2+ established, competing governing bodies.
Second because at least for sparring, karate is formulaic: put fist or foot here, score point.
