Why does Communism necessitate killing minorities, and why are you assuming Social Democracies haven’t killed minorities?
Good question, let’s hope you are able to have a civil conversation!
First of all, every communist regime has systemically killed off their minorities. Social democrat governments haven’t. I hope that clears it up. If you come across social democratic governments systematically killing minorities, let me know though.
Do you think tools have a mystical property that requires the owners to turn evil if they are collectively owned, rather than privately?
Like I said earlier, the underlying economic model under the fascism is irrelevant to the millions of minorities having being killed by communist regimes.
