You do have to tailor the message for the audience, but in this context I think sticking with words and phrases which invoke the whole revolutionary Marxist tradition are a positive. Tailoring your message too far runs the risk of losing some of it. You have to meet them where they are but the goal is to guide them to where you are. When I hear someone say “Billionaires are attacking the middle class” I just tune it out to be honest, because it sounds identical to the background noise of performative liberals, accidentally based for ten seconds republicans, and dead-end utopians. Ambiguously contrarian. I think a liberal will hear it the same way. I want to say “look, we have dusty tomes and academics and structures and traditions and all of that too. We aren’t just screaming into the void.” I think that works, or at least it worked for me.
Not everyone is so apathetic about it. The billionaires building their apocalypse bunkers in abandoned missile silos certainly aren’t. The people involved in ramping up the dehumanization of immigrants, preparing for the cruelty that will be inflicted upon the influx of those escaping man made “natural” disasters aren’t. This is the sort of game which is won or lost before you start playing. It starts soon. We have to build that will now or else.
