You can't organize the working class with a "Marxist" reading list, maga was already told they don't like that word. Speak the ideology of unionization while avoiding the things that can be associated with Marxism, communism, socialism, while remembering they don't understand those things, they just have a trigger words they know to hate.
As an aside when speaking to maga, don't let the conversation ever be Dem vs GOP, always frame is as workers vs elites. In the former we are divided, in the later we have solidarity.
Edit: My response to many responses, I just said dont say marxism or communism because a huge percent of the population are literal sheep who have already been told thats bad, just make a new label, or better yet, just avoid giving it a label, keep it down to "we need to stop the elites/ruling class". Regardless, if you get a bunch of people to fall in line with this ideologically they can label it whatever they want at that point, sheep don't change their minds, so when they villanize the new label, or assign it to a preexisting label, you would hopefully already have enough on board outside of modern left/right bubbles that it can spread through traditional grass roots methods.
