"However, we are all entitled to parent how we see fit and should not comment or judge another parent unless it directly affects us."
I really don't agree with this. It's obviously untrue that it's fine for everyone to parent as they see fit, as social services could tell you, and I think it is fine to discuss on other people's parenting if we think it is affecting not just us, but their child. If you raise a very spoilt child who is rude and difficult to their other carers and people in general because of your pandering, people are going to remark on it. (Not withstanding of course that there are children who are difficult for other reasons, SN and so on, and all children have different personalities, I think it is possible to spoil a child by ridiculous pandering and I think a lot of people do it, as the examples on this thread show.)
I know a family who let their 5yo rule the roost - she stays up as late as she likes every night for example, and can do and say what she likes unchecked because her parents think she should be able to "express herself". Not only is the poor girl badly behaved and widely disliked because she can't handle being told no, she is also constantly in a bad mood because she's exhausted because she doesn't get the sleep she needs for her age. That affects the rest of society, and it affects her, detrimentally. Let's be honest, most of us can see raising her this way is not a great idea and most of us have judgey thoughts about some of the things other parents do. It doesn't mean we're perfect, but it's not all bad - thinking about these things and seeing what other people do that we don't agree with probably helps us to learn and make better decisions.
I'm fed up of this "you can't judge other people's parenting" myth. We can, we constantly do, and so does society, social services, courts and judges. And if you read MN you'll see that people who judge their own parents' poor parenting - myself included - are rightly given a lot of support.
