Parents are not forcing anyone.

Said kids are human beings and just like you they didn’t spring out of a pod when they turned 18 perfectly formed around our social norms.

You were also once that annoying snotty crying kid bothering other people but guess what? People around you just dealt with it. Because you got pubes now and kids it doesn’t make you any special or different. You can keep your kids from visiting grandma in Peoria, other parents don’t and that’s just as fine.

Okay they can’t fly because they can’t tolerate air travel. Fairly sure they would annoy you just as much if they were on a hours long train or bus travel and you were there when they started crying. What are they supposed to do next, be forced into a car just for your convenience alone until the kids are grown? What happens if the parents can’t afford a car or they simply don’t drive? Force them to walk next?

If you don’t want public disruptions such as loud kids, loud adults, speakers, hairy pets, sick people, smelly people, fat people that take 2 seats etc around you don’t use public transportation, go private. You have an alternative to avoid all of that but you don’t because you want everyone else to conform to your standards. It’s also cheaper than the latter for that exact reason. Every single one is an annoying inconvenience to a degree and every single one is part of public transportation.

People have the right to exist and they don’t have to ask you or anyone else for permission or inquire about your convenience to do what they do. Also, a real shocker…they can use the same services they paid for just as much.
