is gymnastics really a sport?

I remember reading on line comments about the last world championships in ice skating (can't really call it "figure" skating any more because figures are no longer part of the competition); somebody said skating isn't really a sport because it is subjective (judges' opinions) and not "objective" (first one over the finish line wins, for example). That made me think--is that person's opinion right or wrong? I see very little "art" in gymnastics any more, but then if gymnastics isn't a sport, then what is it? I remember years ago at the time of the Barcelona Olympics, a co-worker of mine (a man, of course), made a nasty remark about Oksana Skaldina and her nasty attitude toward the Spanish Rhythmic competitor who defeated her, and then he mocked the idea that "twirling a ribbon" was hardly a sport, in his opinion. I knew he was teasing me, though I am sure he meant what he said. I just answered him back in a similar vein, "YOU try it!" What are your thoughts--sport or art? Both or neither?
