Muddle-headed Progressive or closeted conservative teacher with a masterful sense of satire?
It’s an interesting question for sure. In reading both the letters, I agree with the writer: It’s not feasible to know which side of the razor to come down on. Either one is plausible. If he MEANS what he wrote, he needs to be removed from the school IMMEDIATELY and locked into a rubber room. If it’s skillful satire, he’s a MASTER and wasting his time teaching when he could be using that skill to really WOUND the libs.
Definitely satire, and he’s darn good at it.
