Apparently there was a misunderstanding on my part that you were recommending staying in public school, but getting the kids involved in more activities.
Didn't mean to rile your dander
Socially, I think they are just as well off, and usually better adjusted, teachers unions try to use the socialization argument because there is no way to statistically measure that, and it plays on a assumed bias. However socialization and social adjustement tests, if you do want to believe them, do say the kids are fine.
I just happen to think the boy scout, youth sports, etc are always a good idea, it gives kids a chance to play sports and do things with others there age and continue learning values in addition to at home, and since homeschool parents are more apt to be inolved, it gives added value.
