I am certain there are similar examples of children who had been in public school their entire school career coming into high school and doing similar things to what you just described.
just because a child is in public school does not mean they have good social skills
True enough, but I wasn't making any attempt to draw a comparison. I was just reporting what I've seen. Since you bring up a comparison, here's what I can add:
I saw a greater percentage of homeschool kids were are overly withdrawn and don't have social skills, don't know how to relate to other kids. The previously-homeschooled kids I've seen personally are about 50/50 -- about half fit in fine, about half don't. On the other hand, I
can't say that half of the public school kids are socially awkward.
As for negative behavior, I've only seen two homeschool kids -- ever -- who were
badly behaved -- and they were brothers, so it was certainly a matter of what that family had taught the boys. And, of course, I've known
way more public schooled troublemakers.
It's all about what the parents do, not whether the kid is homeschooled or not. But it IS a topic that potential homeschoolers should consider, not just something to blow off as unimportant.
I do think that in some cases you have a child that just may be different and that even if not homeschooled, they would still not have the social skills.
There's merit to that argument. People may choose to homeschool a child whom they believed would've had trouble socially in school, or they may pull a child out of school because he's having trouble . . . so that child will probably still have some social troubles regardless of the venue in which he receives his education. Which is the cause, which is the effect? I'd guess the answer varies widely.
A former student comes to mind: He was a public school student all his life (at least I think), but he probably would've benefited from homeschooling. He had a serious speech defect, and he was extremely shy. He didn't really have friends, and he didn't like school. I don't think he had much in the area of self-confidence. He'd only speak to me if I spoke to him first, and he had a whole host of self-defense mechanisms; he was an unusual kid. He's a kid who probably would've done better in a more private atmosphere.
The point: He would've had the same problems no matter how he was educated, but if he'd been homeschooled he might've built up more self-confidence. Then he could've faced the world later, as an adult.
