It's true that homeschooing isn't for every family or even every child. Our older daughter is homeschooled and has flourished. We tried with our younger in kindergarten and it was a fiasco. She now attends the parochial school around the corner and loves it.
We know many homeschooing families. I assure you that the outcomes are generally very positive and I don't personally know of any negative ones.
I know a girl who was homeschooled, graduated summa cum laude from my university, and is at yale now.
