Like first of all, the guy is pretending the working class is way more reactionary than it actually is. Secondly, who's organizing a group of iron workers in America anymore? Like I know it happens, but they're obsessing over a job that a very small handful of people have at this point. And the entire purpose is to build up right wing narratives of what the working class is, like the left isn't going to magically win if we pretend that the working class is entirely composed of socially conservative evangelical white men who work at coal mines or steel mills.
You bring up a good point about simply holding a position. It becomes obvious how to handle it if you simply reverse the positions and consider how it's done now.
The US government lets us have our leftist forum and identify as leftists on Twitter because that's us just stewing. We're not an identifiable threat to any structure they've built and no amount of stewing will change anything about the current power dynamics. They come after us once we start doing things.
