I wasn't denying that the definition of words can evolve over time, just your ridiculous assertion that essentially words are meaningless because they can be used to mean whatever they want by whomever.Words change to mean the opposite of what they originally meant all the time. 120 years ago, my lean would be called "Liberal."
I think that you would probably disagree with me if I started saying that Hitler's government was democratic, for example.
You won't find anyone that calls themselves a "Stalinist". But it was you that brought up semantics by essentially saying that attaching meanings to words is fruitless because they "change all the time".They don't try to be Marxist at all. They're Stalinist, which has essentially become a type of Communism. You're talking about semantics.
