Well written and something to think about but I have to say it seems like your own experience of homeschooling which was religiously driven has jaded your perspective here more than you meant. That's understandable but it's not as well balanced as the first one. I almost shudder to think how bad the criticisms are going to be when you focus on the religious buttery and "the claws" come out.
These were kind of boilerplate criticisms from professional educators and teacher unions that have been around for decades. They don't take into account the realities of school environment under threat of mass shootings, that we're more connected now with social media and the internet, that the internet now has shit tons of content and resources to help kids learn which takes pressure off parents to be educators. And the kids help each other, which fosters collaboration over never ending competition.
There's Khan Academy. MIT has their entire curriculum and materials available online for anyone who cares to learn. Even lectures are available. You can email questions to any professor just about anywhere and as long as you're respectful, they'll usually try to help you or point you in the right direction. Just don't expect an immediate response. They're busy.
Homeschool groups have really proliferate. Isolation in homeschooling is now a choice, not an inevitable thing. Schools in most places must also open their facilities to homeschooling students, so a himeschooler can be part of the marching band or play a sport or be in the math club. So the ethnic diversity argument is also becoming much more mute. Plus, out on the world outside school and home, minority families are much more seen than they were in the past. They have businesses we all frequent. You can say "hey" and get to know your neighbors and community business owners. Nothing's stopping you.
Point is, most of these boilerplate criticisms came from when homeschooling was in it's infancy. The vast majority have been addressed in large degree by thr homeschooling community, save for the religious nutters.
But those folks are going to be nutters no matter where they are. It might be best to let them isolate and not assume public schools would be safe for them to be there. Look what Moms For Liberty have done to school libraries.
If they were more allowed and even e courses to slither off and self destruct in their little bubbles, poor kids would still have books to read in school. Just saying.
