Your comment reminded me very much of an experience many years ago when I was in my first semester of college. I was taking an elective course titled something like ‘contemporary literature and notable writers’. The prof had a subtle reputation of being a socialist/communist. Among assigned reading we read from writings by world known politicians including Hitler, Lenin and the likes of ‘right wing’ editorial writers. On the final exam there was question/topic to “define propaganda’. I felt this was a better be right gotcha situation. My written answer/response was that propaganda was what we had been experiencing in that class. I got an A on the final and for the course. To this day I think that whatever the prof was politically he had to be fair minded.
If he leans Left he certainly was one of the exceptions and not the rule at least by today’s measuring stick.
