A federal judge ruled in favor of a student in Santa Ana, California. The student alleged that the teacher had violated the first amendment's guarantees of "free exercise" of religion, and freedom of speech.
The teacher, James Corbett, had made comments insulting and denigrating the beliefs of various students in his history class. Corbett told the students that any doubting or skepticism about Darwinism was "superstitious nonsense." Instead of admitting that increasing numbers of professors in the science departments of the world's universities are less inclined to accept the teachings of Darwinism, and asking if there is sufficient evidence for, Corbett rather simply accused the biology, physics, and chemistry department of being unable to "see the truth", and dismissed their questions about evidence as "religious nonsense."
The judge opined that the teacher had favored "anti-religion over religion," violating the right to "free exercise" of Muslims, Jews, Christians, and nearly everyone else. Instead, the teacher's duty is to create "expansive discussion even if a given topic may be offensive to a particular religion."
In short, the teacher's job is to create a free discussion, even about offensive topics; but the teacher may not conduct an anti-religious tirade.
