No, silly. He can teach "evolution" (meaning evolutionary theory of origins of species) until he's blue in the face, and require that students demonstrate knowledge of all the rationale and theory. Just like a professor in the religion department can teach "Judaism" or "Catholicism" or "Hinduism" or what have you. But if getting Federal dollars he can't exercise his duties in a religiously discriminatory way; he has to leave it open to the student whether to profess this kind of "evolution" as personal belief.
So if he taught only creationism and refused to write letters of recommendation (to students who had actually taken his class, that is) to students who believe in evolution, that would not have been discriminatory?
This is what the student said:
Mr. Spradling said that given the professor's position, there was "no way" he would have enrolled in Dr. Dini's class or asked him for a recommendation to medical school.
"That would be denying my faith as a Christian," said Mr. Spradling, a junior raised in Lubbock who plans to study prosthetics and orthotics at the University of Texas Southwestern Medical Center in Dallas. "They've taken prayer out of schools and the Ten Commandments out of courtrooms, so I thought I had an opportunity to make a difference."
What Mr. Spradling seems to be saying this that he couldn't have taken this class because it was a "den[ial] of his faith as a Christian." I wonder if Spradling had taken other science classes, if he plans on taking more, and will he sue if his religious beliefs come in conflict with science?
