One reason is that science is not static especially in the area in question involving evolution and cosmology is another area where far too many school books are filled with postulates that are based more on nice story telling than scientific data. Let the kids learn what they need to in order to make accurate assessments for themselves concerning data, that to me is more important than any of the political issues.
Excluding exceptions and questions does not help produce confidence in Science, what it does is that it leaves the distinct impression on the minds of children that Science is only in a small degree different than religion. Some of the greatest Science was produced by devotly religious men, Let the kids learn what they need to in order to make accurate assessments for themselves concerning data that to me is more important than any of the political issues.
Kant I think had a good idea that metaphysics should be left up to metaphysics and that the hard science should be left up to hard science. The key difference is that he would consider Evolutionary Science and Cosmology not on higher planks than religious thought but on equal and separate planks. Also I think Kurt Gödel's incompletness theorem would be a humbling study for all those involved.
"One reason is that science is not static especially in the area in question involving evolution and cosmology..."
Translation: we need to keep changing the definition of science to make sure evolution still meets the definition (and those wacko IDers don't.)
Science is not static, but the definition is.
