I have the opposite experience. I've met a ton of homeschooled kids (also, I seem to attract them in the dating scene) and by and large I've found they have very sophisticated and healthy social skills, and it's "normally schooled" kids that have very twisted and often destructive social skills, probably derived from mostly interacting in the artificial social environment of "everyone is +/- 1 year from your age". Admittedly it's likely that I am suffering from selection bias based on my own social circles.
