It's really not, and you can look at Trump as the perfect example. He came out and said all the awful shit that Nazis and Klan members believed but rebranded it as MAGA. Socialists could do the same thing, so easily. Just pick a new phrase/word and keep almost everything other tenet the same. Call it "Liberty Forever" and talk about how mandatory profit sharing "guarantees your right to work and access to a free market." It would be so fucking effective.
