My kids are grown. But when they were school age if a teacher addressed them as Comrade he or she would be addressed by me as Target. Their eldest uncle died in 1950 in a Korean town as his unit got pushed back to Busan. To paraphrase Gen. Sheridan, the only good Communist I ever saw was a dead Communist.
I bet if I were to share and discuss my collection of Alexander Solzhenitsyn books (which includes “One Day in the Life of Ivan Denisovich”, “Cancer Ward”, “The First Circle”, “The Gulag Archipelago”, and “August 1914”) as a teacher in one of those schools, that would probably be a fireable offence.
