That's a good on-the-line example.
But really, I just want sport to be about sport. Its whole symbollic benefit is that it provides an alternative to the other sorts of arguments. It channels tribal aggression into a peaceful medium with rules. You get to wear the colours of your country, to compete for your country, or as a spectator to cheer for it. That's enough.
It's not about whether a political position is right or wrong. It's about whether sport is about politics and political posturing. Or whether its purpose is to establish relationships between people who otherwise might wish to kill each other. A lot of people, myself included, prefer it when things stay in their own lane. Otherwise, there's no place you can go and just enjoy a simple experience.
This is why the Olympics first came into being. The Greeks agreed to stop fighting and start competing. Just for a short window of time. Maybe progress can be made by cooperation and competition and not through antagonism and uncontrolled violence sometimes.
I like sports just to be sports and not to become a tentacle of politics. I think that's the reason people boo. They don't want to have politics in the stadium all the time. Maybe it was okay to do a gesture. But to kneel at every game? That's not what people come to see. Save it for when you are off the field of play.
