As someone with good parents, I get very demoralized hearing about how ungodly awful most peoples' parents were. It's so ubiquitous that I almost (almost but not quite) subscribe to the philosophy my friends have where they hold that children should (literally) be raised "by the village" rather than by two parents, which in theory would minimize the effects of one imbalanced mind having full control over the children.
Lately I've been reading a lot of books on narcissism and have been picking up on the idea/notion/possibility/viewpoint that narcissism is a spectrum like autism is. In autism, which itself is incredibly common due to the fact that it's multiple genes/processes/whatever performing multiple parts of a spectrum (think a carpet representing humanity and a shattered cup on the carpet, I use the shards in this visual to represent pieces of the spectrum scattered across humanity, apologies if anyone thinks a shattered cup seems like a negative comparison, I don't), you have the majority of humanity having some variance in it, which goes to demonstrate there's no such thing as a neurotypical. As in, if a scouter was invented that instead of scanning your power level scanned your autism level, everyone would have their very own signature number. ~~I would be over 9000.~~ Same with narcissism, if this view is correct, as it would be another shattered glass on the carpet that is humanity, with the shards from both glasses overlapping in their territories (which when you think about it makes the family dynamics in The Good Doctor all the more awkward, it's one spectrum at odds with another in a show where the main character is a medical savant with autism). And again, not trying to make an awkward comparison, I have friends who openly confess to me they're deep on the narcissism spectrum, and these people at least are trying their best in life, as well as showing narcissism is a neutral condition that just happens to seem more negative in modern urban situations.
Consider this the sequel to my last such question which had a similar idea to it. What's the most narcissisty your parents ever come or came, even if you hold them in generally good regards?
My parents were separated since before I started forming long-term memories and I was raised by my single mother. We used to visit my dad's side of the family for a week or so every other Christmas, I lived with him for a couple months as a teenager when my home life got particularly rough due to a profoundly toxic non-parent influence, and during stay that we ignored each other apart from the cliche "divorced parent and kid who don't actually know each other at all trying to act their respective parts but neither knows how or really wants to or frankly likes the other one but they both know it's polite to pretend" sorts of interactions (which were quite sparing even as those go). Neither of us has ever attempted to keep in touch with the other over the phone or in writing.
To be clear, I don't hold any of that against him even a little bit; that's all perfectly normal on his end as far as I'm concerned. That's all just there for context when I tell you that, now that I'm well into my 30s, I recently heard from my older sister who actually tries to stay connected to him that he's begun boasting about how proud he is for having shaped me into the man I am today. And, like, I'm not even on social media so I'm not a person he's even capable of keeping tabs on from a distance if he tried. He fully has no idea who I am. He not only doesn't deserve to take credit, he doesn't even know what he's taking credit for. I'm just so automatically an extension of himself by virtue of my DNA that he goes around telling other people that he's proud of me.
(A more technically accurate but less entertaining answer to the question is that he's politically a Libertarian.)
