I think this is way too narrow. Following Marx? For sure, you're right.. but if you look at "Liberalism" - which can span anything from "taxes and government are literal hell" to "we support LGBT rights" - and "Conservatism" - which can span anything from Angela Merkel to Trump to follow-my-millenia-old-book-by-the-letter-or-I-will-murder-you - the word "Socialism" in the modern age can definitely contain nuances as well. For instance the main centre-left party in Denmark is called the "Social Democrats" then right to the left of it you have the "Socialist People's Party" - which is far less revolutionary than it sounds - and then you have a few other parties, including one identifying as "Communist" but which doesn't even really fight for any kind of revolution or the total elimination of class but recognises the requirement for collaboration and compromising when in power.

Kinda? Socialism was initially described as a transitionary stage of Communism in the same way as totalitarian violent revolution was described as a transitionary stage of Communism. This view also contained the belief that Capitalism is simply a transitionary stage of Fascism. A mixed market economy then with Socialism and Capitalism then describes an economy that is in a superposition of transitioning to both Communism and Fascism. In reality the transitionary times if you call them that are just as validly real times that people live in and regimes change and come and go and we must strive to fight for justice, equity and self determination while preventing too much power from falling into the hands of too few now and try to find the best system for now rather than acting as though everything is an inevitable slope to one extreme destination and that nothing else matters.
