You ever try to do what Nancy Kwan does? I agree that it is more like ballroom dancing or ballet, but both skaters and dancers are very athletic people.
Just because it's hard doesn't make it a sport, sitting through an Andy Warhol movie is hard doesn't mean it's a sport. Judged events aren't sports, sports are about absolutes, judged events have no absolutes.
And if there was ever a question that figure skating might be a sport that ended Monday in the pairs competition when the female of one pair botched a landing and got hurt and had to leave, only to be allowed to come back later and eventually win the silver. Let's start with being able to come back and pretend they never left, that's just silly. Then winning a silver inspite of that horrid landing, simply pathetic.
Requiring athletic people doesn't make it a sport either, stunt men are athletic, should we have a falling off buildings sport?
