A Columbia University student publicly complained about her professor using the word "Negro," even though he said it in a lesson about 1960s America. The Columbia Daily Spector ran a story Thursday about what happens "when professors make racially insensitive remarks." The paper cited a complaint by student Maria Fernanda Martinez of a perceived "microagression." Martinez said her professor told the class it was appropriate to use the term "Negro" when discussing the 1960's, a time when that was the politically correct term for African-Americans.
