What is your fixation on socialization? Wholesome volunteering? What's that? Teaching children to be a nosy busy body is not acceptable. Keep your kids away from homeless shelters. They are not safe places to be.Unless the parents are keeping the kid out of school in order to focus on some athletic training that may bring in big bucks, HS parents are Nuts and masochists. (-:
I don't think that's reasonable.
Homeschooling is homeschooling. If you do it right, good. Some of the parents who homeschool their children are nuts. Some. Not all.
IF I homeschool my children, I need to have my little ones out and about circulating in the community and socializing. Preferably around children their own age, but it's not a bad thing to be volunteering at nursing homes, homeless shelters, and other wholesome things.
Though I was homeschooled I never did drugs, had underaged sex, or did other stupid things typically seen in the public school setting. Academic standards were much higher than those in the public school setting, too. It takes one or more parents dedicated to making sure their homeschooled child succeeds. I can see now that my case has more to do with a bad father, rather than homeschooling in and of itself. If you homeschool your children you need to have them socialize, and have them socialize a lot. Having been there, if my future wife agrees with homeschooling our little ones I'm hellbound on having them socialize as much if not more than what is found in the public school system.
Just because you're anti-social and proud of it does not mean that socialization is not an important learning process for normal folks.
