I certainly would agree that ID should be taught...
and would go so far as to suggest that it should be taught in the science classes. Very few subjects would be a better medium to show how totally lacking in foundation a subject can be. ID and Creationism (the classic Biblical kind) are great examples of the worst types of pseudoscience. By looking at them it might help students understand the difference between science and pseudoscience. The old examples of the snake-oil salesman are now dated, many if not most students today have never experienced either the medicine man or the carny barker. ID and Classic Biblical Creationism would be better examples of hucksterism as opposed to science and would be ones the kids could actually observe in action.
It could be, but I guess I have a lot of faith in what can be done in teaching. Frankly, I think we could do much more than is being done. Of course, I also believe that to do so you need to throw out all of the elected school boards in the country.
It would be an interesting thing though to look at the CVs of the key people at DI. The issue of whether or not ID is political and social in nature as opposed to scientific can be shown there.
Take a look at what DI publishes on their own website and look at the CVs of their key people. From their very own information it becomes clear that DI is a political and social organization and not a scientific research effort.
