It doesn’t matter if it is or not. When dealing with public space, and especially public schools there has been a determination and precedent set that the school either has to be open to all ideas or none of them. That’s why some schools in majority Red districts had to shut down all of their school’s clubs instead of accommodating a student club composed of gay students which is focused on gay issues. People aren’t governed by a simple majority as it concerns public space, hence the reason why in Arkansas they’ll most likely have to erect a statue dedicated to the Church of Satan (actually true) because they decided to use some of the public space for a crucifix.
Ironically this is the vision which the forefathers had when drafting the constitution and creating a separation between church and state. They didn’t want this type of idiocy to erupt. They saw the government recognition of a particular religion detrimental as many of the early settlers were obviously fleeing religious persecution. Strangely these measures were orginally created to protect the faithful from the government telling them what to believe, and now they want pretty much the opposite and they feel as though they need the government to somehow legitimize beliefs.
It could be taught in a world religions class that was an elective. We had it our high school and I actually took it. The funny thing was that the majority of the the curriculum has nothing to do with Christianity and by studying multiple creation myths it actually discredits intelligent design even more. If it’s between believing a duck swam to the bottom of a great ocean and started piling up dirt to make the earth, or that god created the earth in 7 days they all start to blend into myths of the world, which of course, is fine to study, but as many here have said, has nothing to do with science. The main problem with fundamentalists trying to get intelligent design taught in public schools is that they can’t deal with this fact. Either it will be a little blip, just one of hundreds of theories, or it’s fundamentally dismantled in a science class. What the fundamentalists actually want is a class devoted to their beliefs that goes unchallenged by either other creation myths, or science itself.
Education is a bit different as it effects all students involved of all of society. So teaching ridiculous theories about how the world is 6000 years old, or that evolution doesn’t exist has a detrimental effect overall on everyone in the class. I think it’s great to have small local control on a number of issues, however I don’t know if it should be up to a soccer mom or janitor to decide what’s taught in Algebra class. Academics by its very nature is an extremely heirarchal system which already has a rigorous system of checks and balances in place to ensure what is being studied is throughly vetted and checked. Evolution isn’t some plot created by liberals to try and discredit god (no matter what some fundamentalists believe) and in these cases I think it is better to default to the experts on these issues as opposed to public opinion.
