So it's all about money and the unions I suspect.
well, personally think that it's also about the educational establishment being reflexively and rabidly anti-God.
a lot of the comments on the SFGate article i posted above were anti-religious. the posters were saying, "anybody who keeps their kid out of public school to brainwash them into their fundie cults ought to be prosecuted for child abuse" .. and that was the nicer comments.
most of the parents i know who homeschool dont do it for religious reasons at all. they just dont like all the social garbage in school and they want their kids to actually learn math and history. those kids typically outscore public school kids as well, so it shines another light on how poorly the public education sector is doing.
the public schools there must feel awfully threatened financially to be headed down this path - the parents need to get those legislators out of there PDQ.
