David Fitch,
After studying the natural history of humans for 40 years, I find the best reason why creation science should not be taught in schools is this:
My Dad used to say that a scoop of ice cream on a pile of manure does little to improve the pile of manure. Just a waste of ice cream. But a dip of manure on a dish of ice cream ruins it.
Now, human beings are not designed to learn in schools. Schools for humans is a shitty idea. Humans are designed (you'd probably say, "adapted") to be taught by apprenticeship, in family settings. Schools are for fish, to get them to go with the group. As such, the placing of children in schools to be educated is just a very cruel and dirty trick, apt to make any lively young humans madder than hell and disinclined to trust anything else the scoundrels who run the place are likely to say. It would be a shame to place something as precious and wonderful as the story of creation in such a foul pit of despair.
I once found a course in graduate school that I found useful. I dropped it immediately, although I went to all the classes and took the exams. By cutting out the grades and credit, and spending a lot of time with my major professor, I managed to actually learn something there without losing my mind.
Meanwhile, I watch (cringing) the results of evolutionary teaching in school on the minds of the debaters here that want so desparately to believe that science actually supports the theory's plausibility. Who taught these people how to think? Those teachers ought to be taken out and horse-whipped!
