Crimes against humanity ain’t a minor issue you can ignore. Directly related to communism. Democratic states don’t do that, communist regimes did that a lot: https://en.wikipedia.org/wiki/Crimes_against_humanity_under_... https://en.wikipedia.org/wiki/Mass_killings_under_communist_...

That’s debatable. Might be true in 1910-1920, but by the end of the last century all communist states with planned economy have failed their economies, catastrophically so, with direct consequences on standards of living. China’s the only exception, were lucky to have smart enough people in power to pivot towards market economy, and execute it relatively well.
