I had one like that for several years. His approach to interpretation was that there was his interpretation and “D, factually incorrect”. And that was for homework or tests; having a differing opinion on a work during class was seen as a personal affront.

Notably, out textbook literally started with an essay written by a major author from our country that stressed how interpretation is inherently subjective and how it doesn’t make sense to ask for the one correct interpretation of a text. Of course the teacher never acknowledged that essay in any way.
