You framed it that way, look at the words you chose: racism, Nazism, white supremacy. The overarching ideal of all that can very simply be summarized as "non-white people shouldn't exist". The ideal of collectivism is "power to the people."
It's not bad faith. You need to accept you are working off a different vocabulary. Your shitty media abuses this to stoke the divide.
Neither definition is more correct, but it stands to reason that people arguing in favour of "socialism in politics" aren't Stalinists, for fucks sake. If anyone tells you that, they are trying to rile you up. And if you believe them, you're a fool.
What is the worst possible interpretation of socialism, communism, collectivism, and the new Woke cult?
