Funny thing about history, words change over time.
That was basically my point all along. What “Socialist” means today is often quite different from what it meant originally. In particular, most modern “Socialist” parties advocate policies which are very different from what someone in 1935 might call “Socialist”.
[Though actually “Totalitarian” means basically the same thing today and then; it’s just that back then it could sometimes have a positive connotation, whereas today it’s always negative.]
Given the historical definition of “Socialism”, I agree with you. But since most of the actual “Socialist” parties of the world have migrated to new positions which reject totalitarian socialism, I don’t think clinging to the old definition is helpful. It certainly does not match the views of many self-labeled “Socialists”.
