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.
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.
Assholes are a dime a dozen. Homeschooling doesn’t exempt your kids from learning how to deal with them.
Unless you can magically guarantee (or have enough money to fund their whole life) your children will never have to interact with "problem" people, they will need to learn to deal with those people one way or another. And it's better to do so in a low-stakes situation like school.
