This could happen in your state!
Home schooled children are by far better educated than public school children in many states. What are these politicians so afraid of - they won't get the teacher's vote? That is the bottom line - not the education of your children, but votes to remain in office.
Even more threatening than that, our children may actually learn to think for themselves so that they are not easily led like a bunch of sheep to do the bidding of those in charge. Sort of throws a monkey wrench into their grand scheme!! (IMHO!)
