You would've been right like 15 years ago, but it's changed a lot since then. I live in a place with a pretty sizeable homeschooling community. I didn't come here for that, coincidentally I want to do that for my children as well, it just worked out. Most of the homeschooled young people around here are better mannered, more decent, cleaner, less prone to behavioral problems, and have a larger knowledge base. The days when homeschooling == creationism are coming to an end. There's still a bit of that, but not asuch as you'd expect.

You're right that kids have to be exposed to different people and they need to learn critical thinking and to think for themselves. School does not teach them that, school teaches them that when the drug dog comes into the classroom they have no choice but to comply. School teaches them that they need go go along with social expectations unless they want to get bullied or shunned. School teaches them that it's cool to fight in the bathroom and put the video on TikTok. People teaching their own kids, well that depends on the parents. I can give my kids way better critical thinking skills than school can. Someone that thinks the world is 6000 years old maybe can't, but it has always been that way, we were just pretending it could be different, and what is staring us in the face right now is the reality that that just isn't true. Always and forever, kids will learn to the degree that their parents care about their learning, no number of behemoth institutions will change that.
