You think I'm just dealing with idealized exceptions here? Maybe I wasn't clear enough. I was homeschooled through 7th grade. My oldest sibling wasn't born until I was in 2nd grade, and we lived in the middle of nowhere with no neighbors, so I had virtually no social interactions whatsoever. When I got dropped into 8th grade at a private school, at the age of 11, it was hell. One of my best friends was homeschooled all the way through 12th, moved constantly, and rarely if ever had any neighbors anywhere near her age. Her mother was a fundamentalist, mentally unstable, and abusive.
Though we both turned out all right, I'll be the first to say that neither of us should have been homeschooled. But that doesn't mean it should be outlawed.
Ultimately, though, we're really just dealing in stereotypes and anecdotes here. Unless one of us finds some statistics or studies or something, this can't really go any further.
