Is boxing a sport, JJ? Unless there's a knockout, the winner is chosen by the judges. That being said, I agree with you that ice skating is not technically a "sport", but for a different reason.
My rule of thumb is that a true sport must include defense, a ball, or both. (Golf counts because the course architecture serves as a form of defense, and it uses a ball.)
In the Super Bowl we didn't see the Patriots being awarded only 5 points for a touchdown by "the judges" because they were "ranked lower" and weren't the "crowd favorite", did we? I rest my case.
