I can't speak for anyone else, but these are among the most frequently asked questions we hear, directly or indirectly. This is by far the most frequently asked question of home schooling parents. My initial reaction used to be annoyance. Then for a while I would laugh. It still annoys me a bit, but I don't let it bother me.
Various studies show that the socialization myth is just that - a myth.
It seems to me to be a kneejerk reaction by the entrenched school system to try and stigmatize home schooling, or by the social engineers scared at this loss of control. Despite the emphasis on early formal schooling, some well-respected child psychologists tell us that most kids aren't ready until at least 7 to be spending the big part of their day away from home. Obviously, if you have to put them in school or day care for work, you have to, but it isn't ideal. Young kids NEED lots of time at home with their parents. The point of school is primarily to learn.
