TIL that the Communist Manifesto teaches people to spy on their neighbors and betray their family

I work with this older lady from southeast Asia who had family that moved from China. She absolutely despises China. We talk about it sometimes and she's said the "they hate us for our freedom" shit and apparently has no respect for them because they steal American tech. Anyways, today I made a joke about the Communist Manifesto and she said that I shouldn't read it because it's propaganda and that it teaches people to "spy on their neighbors" and "betray their friends and family". I just made a joke saying that they must've updated it recently and got back to work.
