As for the "insulated from the real world"(whatever the heck the real world is), that is utter nonsense in most cases. Most home schooled children are exposed to a wide variety of situations, people, experiences and circumstances. One of the main staples of most home schooling situations is excursions to experience and learn about what is being studied. These situations require the children to learn to interact with a wide variety of people in a wide variety of social circumstances. Most home schooled children I have had contact with are exceptionally well adjusted, confident and socially aware people.
Most of us agree that academically, you may be ahead
From a social experience "real world" perspective, there are only a few things home schooling doesn't teach children;
1: How to interact, in a very strictly controlled and artificial way, with a group of people who are all within a year of being the same age of each other. It's debatable just how useful this skill is in any situation other than school.
Schools have a range of age groups. Age groups within your class, will show you how to deal with other peers. What you think is normal, may not be when you interact with others.
2: How to be submissive enough to an authority figure who is not related to the child to avoid punishment. Again, debatable as to just how useful this skill is.
Might be the one skill you need to know to save your life. Fight or flight instict. Arguing you are "right" to the wrong person, may have devastating consequences
3: How to cope with forms of social pressure, stigmatization, *******ization and bullying when the system and those in charge of providing some form of protection from such behaviour doesn't do anything about it. Probably a useful skill to have but can be learned from other situations.
You always hear about children brought up in a strict environment rebel...minister's daughters and all that.Funny, there was man at the Roadhouse yesterday, mid 40's, who said he was mesmerized by the tv in the bar, because his wife doesn't allow tv in their home
Just my 2 cents worth but I felt the grossly and demonstrably false generalizations needed to be balanced out with some information from someone who has had some actual experience with home schooling.
