And in an astronomy class, we present literature from moon landing deniers. And in history class, we present information from holocaust deniers. Just to give students a balanced view of all sides of the respective debates.
Don't stop there; show them where else this leads if you let the camel nose into the educational tent:
If we teach that ID is an alternative to Evolution in biology class, then fairness demands we must also teach:
Numerology as an alternative to Mathematics
Homeopathy, Chiropathy, and "aroma therapy" as alternatives in Medical Science classes.
Alchemy as an alternative to Chemistry
Astrology as an alternative to Astronomy
and on it goes, as every form of psuedo-scientific hokum demands a place at the educational table, until eventually there is no time left to teach real science and math in between the time we set aside for all the pseudo-scientific "alternatives."
At that point, America will be graduating ill-educated dunces who will be unable to understand 21st Century Technology, and we we be relegated to becoming a society of superstitious idiots falling for one fraud after another while most of our population will by incapable of doing anything more technically demanding that flipping hamburgers at fast food joints for the rest of the educated people of the world who were taught real science while they were in school.
