Anecdotally, most current or former homeschooled kids I meet seem pretty socially awkward. I wonder if It's because the miss-out on the opportunity to learn how to socialize properly as children. But maybe I'm being too critical, idk.
I have friends in the old country who do homeschooling. They're the kind who do it for good reasons. The amount of controls, checks and justifications the parents have to go through constantly is huge. Constantly prove the teaching methods, program, environment, everything. So there are ways to permit homeschooling that seem better it seems.
