I think there’s like a ton of things going on when people say they hate noisy kids out in public. I think there are those for whom “noisy” is just shorthand for reckless, inappropriate, obnoxious behavior. Which, like, is annoying, and there are absolutely those parents who don’t teach their kids how to act respectfully in public (and often the kids are just imitating their parents who themselves never learned to act respectfully in public) and let them run wild. Or it’s teenagers who, like, it annoys me but also I did some shithead stuff when I was a teen so I can’t really talk.
But there are also definitely people who legitimately hate children unless they’re silent and only spoke when spoken to, that sort of thing. My aunt is like this, it’s shit.
Also there are some things that really annoy me, like babies crying in public, but just because it annoys me, what am I gonna do, ban babies in public? That’s stupid. I mean we do live in a society so you have to expect some minor annoyances when in public, and also most parents realize how disruptive and annoying that is and are usually pretty embarrassed and try hard to get their baby to calm down, so like, we’re on the same page pretty much. Not a big deal.
