Hi Mikey,
I'll concede that some homeschooled children are over-protected socially. However, I have found that to be the exception and not the rule. I have listened to folks complement my children on their social skills (how well they interact with people of all ages, how mature they are considering their ages, how large their vocabulary is as well as knowledge of topics, even current events) and then the minute they find out they are homeschooled they ask, "aren't you concerned about their socialization?" It doesn't make sense. For the record, my children's playmates have been neighbor children, all public-schooled and of various races and ethnic heritages. We have plenty of "different faiths" in our own family and a Buddhist friend living across the street.
The good news is that there are plenty of educational options out there and homeschooling is but one of them. Parents are free to consider all the options and choose what is best for their family.
That about sums it up. Alas there are far too many, and all sides of this issue, that refuse to see that simple truth.
