I’m not understanding your view that sports are not a game. They literally make video games based on sports. You keep score. There are rules. There is some skill involved. There are winners and losers. It’s a game.
You’re conflating what some fanatics do to the entire sport. That is not how YOU have to engage with it. Most people casually watch sports. It’s just entertainment like watching a movie. Can it be harmful? Sure. So can drinking water. But blaming the sport instead of the irresponsible individual is unfair.
