My wife grew up in the PRC. Before Communism they were a very prominent family (her great uncle was a literary pioneer; his brother, her grandpa, a judge prominent enough that he was mentioned in the movie
Lust Caution; and their brother a successful MD), and as a result were "black" under the Communist regime.
With the exception of my wife's grandmother, every member of her extended family spent time in either prison or forced-work camps. One of her aunts translated for me the "confession" she was forced to sign. None of this was related to what we'd consider crimes, but was entirely political.
The Communists took the family's house. They had a refrigerator and a piano, which the Red Guard destroyed on the basis that if everyone didn't have such bourgeois goods, then no one should. When TVs were made available for neighborhood viewing, my wife wasn't allowed to attend.
And there's the malnutrition and squalor they were subjected to. They shared one floor of a brownstone with 2 other families - so, 3 entire families sharing one kitchen and 1.5 baths. There was insufficient food, to the point where they had to eat insect-infested grain - while Party members got plenty.
So, all in all, my wife's experience with Communism wasn't positive, and having lived through that, she's the first to speak up against anything that exhibits any of those traits.
