Would you object to a school board mandating teaching that astrology is a scientific alternative to astronomy, or voodoo as a scientific alternative to medicine?
The school board mandated nothing. Let's stick to the facts. See the above post.
I would object, but not on constitutional grounds. I would vote to remove the school board. I would use political influence to change it and not the courts.
BTW much of what we consider "medicine" is in fact "voodoo." In testing drugs the placebos are often found to be just as effective as the actual drugs.
