Nowheresville, USA has a nice post about some bad arguments for not sending your kids to public schools, followed up by an equally good second post.
There's also a third post, but his skill in responding to the arguments against public schooling doesn't manifest itself in his arguments against homeschooling, which seem to me about as bad as the arguments he's responding to against public school (note the false empirical claims about what homeschooled kids turn out to be like; see my comment). This is one of those issues where it's just overreaching to claim you have a conclusive argument for or against any of the major positions. I can think of about four or five major views you could take about schooling, and each one of them is false if taken as the only legitimate way or even as the best way for all parents and all kids.
Apparently The Dane is planning at least three or four more posts, so this will be a major series. [Hat tip: Jollyblogger]
