Yeah, the libertarian take (intentionally lower case, BTW
) is right I think.
Any time ANYTHING is paid for by the government it is ALWAYS political. Science, schools, whatever. This is, and will always be true. If your money is tax money, then political representatives decides who gets it and how much.
The science, for example, is annoying. The fundie take is 100% wrong. Not debatable, sorry, it's fantasy. But since the schools are political by definition, they might well get creationism nonsense in there at some point—luckily this always gets bitch-slapped in court.
Going all private has some positives, but then we'll see a balkanization I fear. Muslims in madrassas, christians being trained to be equally stupid in their schools, etc. On the plus side, those of us using good private school will save tax money, and still train our kids to be the ruling class (in every serious discipline) over fundie morons.
