The HSLDA is one matter. But this article is unbalanced, in that it leaves one to assume that homeschooling is an insidious thing that only religious fanatics engage in so as to have the ability to abuse their children.
The National Center for Education Statistics shows that homeschooling is a growing, nonpartisan phenomenon, engaged in by both conservative and liberal political families, the common denominator being a lack of confidence in the quality of our public schools (with deterrence by the cost of private).
(So, ironically, any group that believes that homeschooling is the bane of our society could potentially kill homeschooling by supporting a voucher program allowing school taxes to follow the child. But, homeschooling foes are almost always voucher foes as well, leading one to the inevitable conclusion that their agenda is not the well being of children, but the primacy of the public school system over all alternatives.)
