A lot of people are saying that your view of home schooling is wrong, that they of course don't protect their children in a bubble like you say.

My personal experience with friends that where home school would agree with your view. They where all home schooled to 'protect' them from undesirable beliefs and ideas. The parents (of the kids I know) would also disagree with you. No one wants to think that they are over protective and hurting their children by protecting them.

I wouldn't say all home schooled kids are like that, but I wouldn't say that none of them are either.
