Religious expression in public colleges may be limited at Temple College in Temple, Texas. Limited, that is, to affirmations. At least, that is implication of this report from Inside Higher Ed. A philosophy professor was told to remove from his door a cartoon based on 2 Kings 2:23-24 because it included an expletive, which people might find offensive. That passage of scripture describes the story of Elisha, after being taunted by children for his baldness, cursing the children, who are then devoured by two bears. The professor, thinking that the offending element of the cartoon was the expletive, replaced it with a quote from Nietzsche, God is dead, in the original German. The professor was told to remove that quote as well, as students found it offensive. Read the article for more details, including statements from students who assert that pro-religion quotes are treated differently at the college.
I don't know about you, but I find the intersection of private belief and public institution to be a fascinating place to stand and observe people as they walk by.
