No one told you that you have to feel guilty. But if you were on the wrong side of the inequality, I don't think you would simply get to escape it. It's always there, so yes, better to see it. Doesn't mean that you're not allowed to have fun, play games, make love, buy frivolous things or any of that. No one's talking about regulating your pleasure. I'm just saying that, yes, it is in fact a privilege to get to pretend that one lives in a world where sports in a simply a non-political realm divorced from social conditions.
It's easy to nod along and say "come on, stop complaining, you need to be aware of this stuff" when you already agree with the views being peddled. If Colin Kaepernick and friends had been taking a knee to protest against abortion instead of police shootings, I suspect you'd be singing a different tune real quick.
If fullshark were on the side of inequality, she probably wouldn't feel guilty about it. She'd be delighted every time it came to light. "Do you know whose lives really matter?" she'd say to some kneeling footballer with a grin on her face, "millionaires'!"
It's the people that mostly agree that are being annoyed and turned off by antics that make everything political.
