If someone is being bullied because their parents have intentionally withheld age appropriate social opportunities I'm order to feed their own egos, leading them to have a deficit, then it is exactly a skill issue.

If, as hypothesized, the child was already behind in social aptitude, then completely exempting him from the world of children and fast tracking to adulthood is hardly the solution. It would only male the situation worse. Regardless of the behavior of other kids around him this is really setting up to fail down the road.
