No doubt there are introverted homeschooling families that can be a bit strange. I'm not sure that kids like that do any better in public school though, because they implement damaging social coping mechanisms and tend to get bullied badly.

The majority of homeschoolers I interact with are more socially capable than other kids. They are used to being in the actual real community with typical adults. They speak up for themselves, can navigate playing with a mix of ages and have better foundational emotional attachments so their overall levels of anxiety, depression etc. are far lower.
