I would be curious to know just who the people are in this "Home School Advocacy Group"? We have enough government interference in our lives already.
Last time I checked, the right to life, liberty and the pursuit of happiness are supposed to be protected by the constitution.
I don't see government background checks being any part of those three things mentioned as far as I am concerned.
The Home School Advocacy Group may very well be a covert government run operation disguised to look like a home school group of people.
