Like I'm pretty sure the conclusion I had was "oh haha I see your point mr. Vonnegut, too much equality can indeed be a bad thing!"
And I definitely don't remember my teacher suggesting anything about it being viewable as satire of red scare paranoia either
Religious fundamentalists are everywhere in my hometown. One time as a kid my yugioh cards were confiscated and they tried to pressure me into admitting they were tarot cards, since they wanted a record of me practicing Satanism. We were also never quite taught evolution either. The teachers danced around the subject completely.
