Tankie is a pejorative label generally applied to communists who express support for one-party communist regimes that are associated with Marxism–Leninism, whether contemporary or historical. It is commonly used by anti-authoritarian leftists, including anarchists, libertarian socialists, left communists, democratic socialists, and reformists to criticise Leninism, although the term has seen increasing use by liberals and right‐wing factions as well.[5][6]
