That is the biggest urban legends against home schooled children promoted by teachers unions. Many non-union sponsored research has shown just the opposite. Home schooled children have more: 1) personal integrity, 2) higher ethics level, 3) less prone to mass suggest and propaganda, 4) less sexually promiscuous and teen pregnancy, 5) much, much less illegal drug use, 6) less sick days and most of all 7) biggest cause of public teachers union loss of retirement pensions.
Get the facts first dude!
Actually, you need to get the facts from unbiased studies on this. All of the studies where home schooling appears successful, the studies are not blind studies at all. They are heavily biased sample sets.
I am glad you are supporting your kids, but please don't try to preach you are better than the rest of us in your approach to schooling.
