My observatiom has been that a lot of unschooling families have parents who do it because of their own neuroses and are otherwise ill equipped as parents. Conspiracy theories and fringe religions are common. Emotional manipulation and abuse is common. Isolation and poor social skill development is common. Important childhood experiences are restricted. Often these parents don't want their children to succeed and leave the nest.

I'm glad you had a good experience, and I am sure there are a lot of people who do when their relatively well adjusted parents commit to homeschooling their children. I just suspect most homeschooling experiences aren't like yours. I've met several families from very different backgrounds with a similar outcome to mine.

Prior generations had more of that, but the more recent trends have lots of support groups for home schoolers, where you get more socialization and support from other families.

Parents are increasingly opting for home schooling to get away from bad or ineffective schools, rather than for purely religious or psychological syndromes.

It is also a lot easier than it used to be. The internet hugely improves access to materials. There is a vibrant online community to discuss and get help.

Speaking from first-hand experience, the positive and negative experiences aren't mutually exclusive.

I might be a college-educated autodidact who made an entire career out of self-taught tech skills but that was despite a parent trying to raise me as a young earth creationist and despite all kinds of still un- and underdiagnosed trauma and disorders. Didn't get my ADHD diagnosis until my late thirties and still haven't been diagnosed as autistic, among other things, all of which likely would have been glaringly obvious to public school staff.
