That is true. But to be fair Communism was a Western European invented ideology. So who are we to judge? I mean WW1 and WW2 nearly ended European civilization if not for America to take up the slack. Who knows? In the long term WW1 and WW2 (and the Cold War) could have destroyed the European and American Western Civilizations.
I tend to think that Communism was merely a convenient vehicle - or protocol, if you will - for the continuance of of a cruel culture that treated the majority of those who lived within it as chattel.
