Yep. I got even though. I took a full-year course on Yeats in university, and the teacher clearly did not want to hear any opinion beyond what his own thesis was all about. The major portion of our grade was an essay, topic of our choice. He had commented ad nauseum that he thought Yeats's mysticism and involvement with The Golden Dawn was a pile of crap invented by weirdos and/or hippies, so I decided to write my paper on that topic. I researched more than I even had before, cited resources from folks Yeats actually knew. It was a lofty tome, and incredibly well-referenced, if I say so myself. I got an A. He had no choice.
