Maybe it doesn’t to you, but it’s such a tiny tiny thing to ask of someone to stand for a minute and take their hat off, is it worth making a stink over? Imagine if the country still called ball players (and everyone else) to serve in wars instead of expecting them to stand for a song. Bet you they’d rather stand for a minute.
and besides you’re free to do whatever you want as a fan. Someone might give you grief but that’s about it. Not sure if the teams require it or fine players who don’t stand. When I worked in minor league ball some guys would go up the tunnel during the anthem. Doubt they ever got fined. It would just look a little more respectful if everyone was on the same page.
