Nowadays that's no longer on the table of "allowed critiques of socialist regimes". Now you have to go by stuff like:

• Social engineering.
• Modern culture war bullshit somehow shoehorned into that period.
• Culture war urban legends like a Hungarian football reporter being forced to refer to a player "the white sock player" instead of "the black player" (football players have numbers on them for easy identification).
• Giving people welfare instead of work (most of the Soviet Bloc had mandatory work).
• Not having a strongman leader like Donald Trump or Viktor Orbán, because these morons think it's called that because it's a good thing.
• Claiming crime was rampant due to "lack of arrest quotas" (some states had arrest quotas, and regularly ended with tragedies).
• Inventing some fake famines, because people need to claim communism = famine. This lead to people claiming Hungarians not eating beef like Americans is due to a famine. Hell, they even call banana shortages "famines", just to hammer this talking point home.
