Dana Goldstein tells you why in an essay in Slate. She suggests that…
Over the past year, there has been a resurgence of interest in homeschooling—not just the religious fundamentalist variety practiced by Michele Bachman and Rick Santorum, but also in secular, liberal homeschooling like Taylor’s. Think no textbooks, history lessons about progressive social movements, and college-level math for precocious 13-year-olds. Some families implement this vision on their own, while others join cooperatives of like-minded, super-involved parents.
And the heart of the matter?
This overheated hostility toward public schools runs throughout the new literature on liberal homeschooling, and reveals what is so fundamentally illiberal about the trend: It is rooted in distrust of the public sphere, in class privilege, and in the dated presumption that children hail from two-parent families, in which at least one parent can afford (and wants) to take significant time away from paid work in order to manage a process—education—that most parents entrust to the community at-large.
Overheated hostility toward public schools… that sums it up nicely. Read it all. And take your complaints to her (or him- who knows. Dana is one of those names you can’t really tell the gender of its bearer).
