My son is homeschooled and has aspergers. But how it has affected him is that he thought for years that no one is his enemy and everyone is his friend. He never had trouble going to a park and finding someone to play with because he was oblivious to the rules that you have to play with only kids your exact age or that acted cool or whatnot.
As he has gotten older he doesn't care to socialize with the whole world and he can make people's eyes glaze over when he goes on too long about something, but he has never been an outcast.
My dd is homeschooled and NT. Even in established groups (Softball, Scouts) she has not foud a "friend" though people are plently friendly to her. But it has nothing to do with not being around kids enough.
My next dd is in public school and has aspergers. She doesn't WANT to join in most things and is content to stand on the sidelines. But for whatever reason people still like her.
We put too much stock in HS as the reason kids are awkward or not. Awkward kids are anywhere. Shy kids are anywhere. Kids that leave others out are anywhere and kids that join everthing are anywhere. If your kid is at the park or other place in society on a regular basis, the awkwardness she may or may not have is just personality.
