Wikipedia is an encyclopedia, not a venue for pushing your own POV. You are the user who wants to change a stable and sourced and unproblematic wording, not me. Stalinism, for the record, is one form of communism, among competing communist ideologies. Removing communism is totally unacceptable, but I don't see much difference between the old wording and the most recent one. All communist/Stalinist, fascist and Nazi regimes are totalitarian by definition.
