This has happened to me a lot. I often challenged my fascist in class. Also dropped me down a full grade even though I was always an A student. But I didn't care in my Master's program. The younger kids watched me and I believe I taught them not to drink the Kool Aid AND the it was Kool Aid. lol.
My college experience was similar. It was an adult studies program, and the people attending had been around long enough to know a thing or two. The college profs they recruited were used to intimidating and brainwashing a bunch of kids right out of high school and had no experience teaching actual adults with life experience and firm convictions. We made them squirm and flustered and eventually so frustrated that most of them never came back for subsequent semesters. The only exception was the English teacher who was a crusty little Vietnam-vet Airborne troop who described himself as “slightly to the right of Attila the Hun.” He hated his colleagues as much as we did and was tickled when we go their goat.
