I hear this all the time, but so far every time I've met a home schooled kid they show that lack of socialization. I'm not saying it can't be done, but it is so rare that I doubt any home schooled kid is.

Sure they will have a lot of kids, but that is not the same. Do they interact with kids that are different? Poor, rich? Different religion? Different political background? (note that many private school suffer from the same problem - generally not as bad as home schools, but it is easy to find private schools that don't really socialize kids well either.)
