I couldn't agree more. Home schooled children draw from a rich and varied social community. There are however always "fors" and "againsts" whether it's home schooling or state schools, and different ways of looking at these things.
Aside from parents who don't make an effort in either situation, perhaps another way of looking at it, is in a similar way to parents who choose to work as opposed to those who choose to stay at home to look after their children.
"What is good for the parent is good for the child !!"
