I don't think that contradicts any of what I said. If people have a principled objection to public school, good for them. They should have the right to secure an equivalent education any other way they choose ... but it has to be equivalent. If not, too bad. Parents aren't allowed to feed their children sawdust instead of food, and they're not allowed to fill their their children's heads with religious/libertarian dogma instead of an actual education, for the same reason. Either would be a violation of the child's rights, and that's unacceptable in a civilized society.
