I know a lot of homeschool kids, and they're all pretty well adjusted because they engage in social stuff outside of school work - church, sports, music, outdoors stuff, jobs, etc. If anything, the homeschooled kids I know are better adjusted because they're exposed to society outside of the fucked up artificial setting that is a classroom. They learn to interact with people in the real world. The private and public school kids I know are all neurotic and think that classroom society is the same as the real world.
