Here at GetReligion, the “F-word” always catches our attention. It’s a loaded word that can carry a negative connotation when applied to religious groups or institutions.
The Associated Press Stylebook — “the journalist’s bible” — contains this entry:
fundamentalist: The word gained usage in an early 20th century fundamentalist-modernist controversy within Protestantism. In recent years, however, fundamentalist has to a large extent taken on pejorative connotations except when applied to groups that stress strict, literal interpretations of Scripture and separation from other Christians.
