Correction: "commies" has always been a weaponized label for anyone with empathy and raising concerns about the externalities caused by rapacious corporate greed. Right-wing death squads murdered journalists, whistleblowers, and activists, slandering them as "commies" to justify extrajudicial murder. Banana wars, the Shah, Pinochet, Iran-Contra, regime change, and more.
Way more broad than that. My right-wing family refers to all liberals as commies. Personally I've never met a real life communist. Even the most liberal of my friends are at most moderate, many are still right-leaning by any definition not created by the GOP.
