Last week, after returning from an interview on a network that makes liberals cringe, I came home to an inbox full of emails. Usually, when I come home to a full inbox, it’s because a professor has done something stupid and people want me to write about it. This was no exception. A professor at West Liberty University had banned Fox News as a source and told her students that the "biased" station makes her "cringe." That kind of thinking is common among professors. But few professors are stupid enough to reveal it in a syllabus.
