Childhood and youth are anything but “low‐stakes.” The social experiences I faced in public school were far worse than even the worst parts of my adult life. The direction I was headed was one of dark cynicism and misanthropy thanks to the bullying I faced and the lack of care from the adults in the system. When I switched to homeschooling, I began interacting with rational adults (my parents’ friends) and in turn learned what functioning human relationships look like. My ability to weather the difficult storms of adulthood in a healthy way came from the social growth I gained through homeschooling, not the regressive “socialization” that public school inflicted on me.
I had exactly the same experience. I was in a public school full of assholes and teachers that couldn't care less about any bullying taking place. Those few years were probably the worse years of my life.
I grew significantly and became a different person when I was moved to a different school.
I still think it taught me a lot about the world and how people really are. I really lost a lot of faith in humanity in those few years and still see the world as cynical in which all people are in it for themselves.
Did it make me stronger? Maybe. But also I wish I could see the world more positively as a lot of people that have been shielded from those experiences seem to do.
On the opposite end of the spectrum I grew up near a Mormon family whom exclusively homeschooled their children. Their 'homeschooling' mostly consisted of using the older children to assist and babysit the younger children as they had about ten or so children, and naturally could not equally provide schooling for such a wide range of needs.
They were a nice family, but when I was in community college I had a chance to talk with one of the eldest who was there getting her GED. Last I recall, she held some resentment towards her parents because she was held back fairly significantly by her upbringing. Well, except for the fact that they were wealthy which helps smooth some of the problems.
