My sophomore year world history teacher was a Korean War vet chud who demonized communism, and lovingly told us the story of how calling someone a pinko commie back in the day were fighting words.

Interestingly enough, he also taught about the history of several different world religions from a completely historical point of view, no injected Christian worldview or anything, which led me to begin questions my faith and upbringing (Southern Baptist) and curiosity into other religions, which led to my then agnosticism (but now am converting to Judaism)

I also had a thing with his daughter later in hs and that enraged him because I was a girl at the time, and that was hilarious

Edit: I almost forgot. he was also surprisingly pro union and paid a lot of attention to teaching us about labor movements in the early 20th century; I remember watching Matewan, a movie about a coal miners strike. He also commented a lot about how unions were important and how often strikers were massacred.
