> This used to be nigh unto a human universal: your parents raise you up from a helpless infant to adulthood, and this obliges you to love and care for them for the rest of their lives.
Alternate take on that human universal: your parents had unprotected sex and fulfilled their obligation to raise the offspring produced to adulthood, this obliges you to nothing.
I'm not saying this means everyone should estrange their parents, but the idea that a child has any obligation to their parents for raising them seems misguided at best and damaging at worst, imo. Any attachment between children and parents should be due to mutual feelings of love and respect, like any other relationship - if those are absent on one side, why should the other suffer a relationship with people who they would otherwise remove from their friend group?
(Note that I have a good relationship with my parents, so this isn't coming from a place of personal pain, but rather a dislike for the idea that two humans procreating and fulfilling their obligation to the offspring that comes of it should impose any obligation whatsoever upon that offspring.)
EDIT: I should clarify that I do believe that parents who went above and beyond that obligation to show their children love and respect and receive nothing in return have a right to be upset - however, what about situations where a parent thought they were doing the right thing (based on how they were raised, religious briefs, parenting advice from a friend or magazine, etc.) but the thing they were doing was actually harmful? There's a lot of nuance in this, but I think that a blanket "honor thy father and thy mother [out of obligation]" is a bad idea.
