Judgement is only partially the problem. You are never as full of yourself as a parental figure as before you become one. Neglectful parents should be held accountable, that is not the core of the issue.

What bothers me immensely is the thought that "your kid, not my problem, but actually it is my problem, because I want them to behave differently". This is like eating your cake and have it too.

The other thing that I find awful is that just existing on the outside (for some families even inside) is so anxiety evoking because of all these judgements. Parents end up micromanaging their kids and berating them for minor things because they are so fucking scared that people will judge them or yell at them for not having a picture perfect child that you can overlook. Children are not allowed to show any childish behavior on the outside. And this is what bothers me so much. You have to constantly choose between supporting your kid and gentle (not neglectful) parenting where you don't yell or hit and simply being on their side or trying to appeal to the scrutiny of the public eye because it wants perfect order and quiet.

When you go vacationing in a child friendly country (looking at you, Croatia) and you feel supported instead of frowned upon for the exact same behaviors of your kid, because they are just having fun and not destroying anything and just minding their own business while not perfectly sitting still, then you just understand how shitty it is to go every day feeling the cold stare of everyone around who wished children would just die out.
