I briefly dated a girl who was homeschooled. She was a very nice girl, but holy fuck was she awkward in social settings. So many references that people our age should get would go right over her head. She was also from a well off family so when she didn't get these things, she kind of made it out to be like a class issue. "Oh that's from a rap song is it? We were never big on rap in our household." Well, we're you living under a rock? You don't know to the window, to the wall?
I will give her parents credit. She was very well read and learned to play a lot of instruments. She was very knowledgeable of the arts, but anything pop culture related was clearly a no go in her childhood/ young adulthood, and it made her quite dull.
Her brother was also fucking creepy man. I got real serial killer vibes from him. They were socially very similar, and I'm pretty sure the brother was closeted and gay. I had just assumed that he was out by the way he spoke, and acted, then one day she said something about how he needs a girlfriend. I said something along the lines of "are you sure he's looking for one?" And she got super offended and said she doesn't know why everyone thinks her brother is gay, and that men always hit on him which he supposedly hated. That could also just have been a lack of socialization and picking up on societal norms? Maybe he actually was straight, idk but he acted and looked very much the part. All in all the vibe was super off with them.
I think kids need to socialize to develop correctly. That girl, her brother and the handful of other homeschooled people I've met in life very much have reinforced that belief. I especially am worried about this current crop of anti vax types with little to no critical thinking skills home schooling their children. The HBO documentary - "This Place Rules" covered this briefly, and I worry for those children. I have a friend who has similar fringe beliefs and has talked about homeschooling his kids. I hope for that kids' sake they actually send him to school because if not, he'll be sounding like the kids in the video below.
