Violence, suppression of dissent, and coercion are the hallmarks of hierarchical, authoritarian and totalitarian regimes, not égalitarian, democratic societies.
There are/were several, high profile countries claiming to be socialist or communist: The USSR, Nazi Germany, Fascist Italy, China, Cuba, &c. These were authoritarian, hierarchical, coercive, and questionably democratic. They were hardly "worker's paradises' or "Peoples Republics." They were everything Socialist philosophy opposed.
But the right-wing in the US capitalized on the name, with Red Scares, removal of socialist curricula and professors from universities, and a massive, well funded, anti-communist publicity campaign.
To this day, the average Joe knows little or nothing about socialism or socialist history, or any political theory, for that matter.
