What if the parent is just having an off day, and is truly the best parent every other day of their lives?
Then the kids wouldn't behave like brats in the first place. There is a difference between behaving badly by accident and doing it consciously. If a kid scream and yell because they hurt themselves, and the mother tries to comfort them, but are having a headache and generally doesn't feel like they can handle it, it is a lot different from "I WANT THAT XBOOOOOOX!!! YOU W****!!! F*** OFF!!!" and the mother giving up and buying the xbox. She might have a bad day, but the kid obviously know how to get stuff. You learn pretty fast that screaming won't give you anything but negative attention and most likely being locked in the car and stuff, and that behaving well will make the parents more likely to listen to your requests.
But what if the parents are just imitating their own parent's parenting style? What if the parents were told to act this way by some parenting book? Basically, you are blaming the children for imitating someone who is in turn imitating someone else (and who is in turn imiting someone else and...).
They are doing it wrong, either way. If their parents were giving in and letting them do whatever, they won't let their kids have whatever, because then they grew up to be spoiled brats, and would most likely neglect their kids rather than give in to them.
If a book tells them to do so and so, and it doesn't work, and they still continue because the books says so, it is the parents' fault. Common sense might not be very common, but if you can't change your own behaviour and care to find a way to get to raise your kids properly, then it is your own fault.
That being said, what I find rude and annoying is the people who are unable to control their kids, and doesn't care/has given up/think they are doing it right and everyone else should shut their mouth. Every parent have their own trouble with kids, but there is the difference between those who try, and those who doesn't.
It is like the issue with the parents that are selective blind to their kids' problems with weight, and will deny any evidence, expert or whatever that points towards it. Because obviously there is nothing wrong with their kids. If there was a problem, it would mean they would have failed or at least have made errors as parents, and they are ttly the best parent evar, so that could not be right.
Just because the parents thinks it is right, does not make it true, and does not make it the kid's responsibility.
Though I will note that this only is true up to a certain age. After that, the children know what is right or wrong, and just decides to not care about it. It is still the parents' responsibility to handle their kids either way, even though the child is consciously misbehaving.
