Oh, okay then. There's no discussion to be had. Homeschooled kids are isolated from society. Society doesn't get them, they don't get society. All's well. When can we start sending anthropologists to study their primitive society?
Isolated from a part of your society but still very active in the rest of it and replacing what they're missing with a similar society of their own. Society as a whole probably can't tell the difference once they enter the workforce. It's not much different than a person that simply went to a different school system than yours.
