What a moronic argument.
They argue that the school board's policy essentially promotes the Bible's view of creation, and therefore violates the constitutional separation of church and state.
If the purpose of a school is to educate, and if there is a credible view that runs contrary to accepted opinion, are we going to discard that view eventhough it is substantive?
I don't see separation of Church and State being at odds with what is taught in school provided that what is taught is school has the requisite educational grounds.
Using the opinion of those people, then a class session on how to perform bestiality without injuring oneself should be taught since it does not violate separation of church and state.
