Sport (Noun)
An activity involving physical exertion and skill that is governed by a set of rules or customs and often undertaken competitively
Logic disagrees with your opinion, so does the dictionary and most rational thinking people. While I do agree with some aspects of what I think you are trying to say, saying judged athletics are not sports is flat out stupid. Yes, there's way too much emphasis on the human mind, and plenty of room for bias, that still doesn't take away from the activity. As I have said, I have seen fat ass baseball players who can throw a ball or hit real hard, and I have seen a skateboarder who has broken his bones many times yet still trains and gets back on the board, or a gymnast who's essentially sacrificed their life for the sport they compete in, all of the above are different types of activities involving physical exertion and skill that is governed by a set of rules or customs and often undertaken competitively.
