I see that you’re offended by the title. But it appears you haven’t read the article. Which is ironic because the point of the article is why you can’t judge someone based on what you see on the surface.
There’s a difference between taking responsibility for your child’s behavior and blaming everything your child does on how you did as a parent. The former is something you can build on and grow with and improve on. The latter is judgmental, condemning, and doesn’t help anyone. It also does nothing to recognize the complexity of children’s behavior (and parents’ behavior), which you do seem to recognize in the first part of your comment.
I wonder if you’d have a different viewpoint if you made it past the headline and read the entire article. I’m not at all saying parents are free of responsibilities. The point I’m making is that when you spend a limited time with a child, whether she acts “good” or “bad” is not something on which you should base a judgement on her parents’ “goodness” or “badness.” It’s easy to say, “your kid behaved well! You’re a great parents,” but then the flip side is “your kid behaved terribly! You’re awful parents.” An improvement would be to save the judgments and accept that things are always more complicated than what you see on the surface.
