"Disgusting" is an interesting description. Humans by nature are competitive. Competition pushes us to achieve bigger things. Not just in sport, but in life. Is that "disgusting" too?
Well, I said "mostly" but... it can definitely be.
I'll object that
- You are assuming that, since I don't like this kind of competition, I don't like any kind of competition. That logic doesn't seem to work. There are many forms of competitions that do not involve sponsoring very bad companies. I think they're better.
- "Natural" means almost nothing and doesn't qualify things, like... ever. It just means that we observe it to happen. And it's even less useful when used to describe human activities, since its alternative is "artificial". But thinking something is good because it's "natural" is a pretty common fallacy. Food poisoning is natural.
- Our competitive "nature" can surely have terrible consequences. War is one of them, there are others. To me, risking your life for money and glory is also not good.
- There are pretty good alternative drives to do good things to competition. Like the will to do something good which isn't "impress others" for the sake of it that many people seem to show. We should take as an example one of those people instead.
- Calling sport victories a "big thing" is debatable at best. Especially if that sport is mainly driven by really bad interests.
I'm against all aura of holiness the world commonly puts around sports, which allows them to thrive in spite of all ethics. Except for the farce of "sports ethics" that makes people say "wow, such a fair player" to an millionaire football player who gives the ball back to another millionaire in a stadium built by slaves. Like... this literally happens and people think it's fine and not laughable.
