Again highlighting that private schools/homeschooling would solve this problem entirely. Let the people who don't want to learn science learn babble instead (flat earth, 5000 year old earth, fossils are tools of satan, quantum mechanics is secular-speak for Jesus, etc). That way, they only destroy their own education. They want to stay pre-enlightenment, great for them. They'll have company in a few sandy countries.
The only trouble with what you're suggesting is that their children, who don't deserve it, will be cheated out of an education. Bad education carries with it many negative externalities, which is why it makes good sense for the government to ensure some minimum education standards.
Now, don't get me wrong. I'm not an advocate of public education, just some form of government accredidation or certification of certain minimal standards in science, civices, history, geography, and literature.
And creation science most definitely should NOT receive any government accredidation. Home schoolers MUST teach their children about evolution. If they want to teach them some stupid "alternatives," well, then there's not much we can do to stop them. But their children must have a solid grasp of evolutionary theory.
