What is to be done in America is a complete capitulation of the cultural and the middle class sphere of politics. American progresivism, one that couldn't just be countered by a simple light-reformist release valve, is dead, only small embers if it remain that will fail to reignite its former self.
If you accept this, then you can accept the deeper truth - that the "foundational American values" are nothing but a big fat lie, a slimy pacifier for the sleeping middle class potatoes. And even then, only the most malformed of these lumpen truly believe in them, as shown by the urbanite liberals, so happy to kiss the jackboot of the state when its used against some brainlet rightwing thugs (to call them terrorists is a cruel joke), or the migapedes, so joyous with having a big government so long as it passes laws that "triggers the libs". No one really cares about "bursoot of freedom :dDdDD", so neither should you.
And with that in mind, an actual vision of what is to be done can be seen. Since burger values are fucking fake, the concept that xyz is too radical for the US, or that it would never fly because muh ideology, is also wrong. This means, that the spooky scary and uncool leftist tactics of old, to the dismay of shmashies, post lefts and Morpheus cosplayers, are just as valid as they ever been. With that in mind, just look at your country - look past the retarded urbaninte liberals and their fraternal suburbanite Republican rivals. Look past and see the shithole that your country, outside the gated boomer safe havens and stratified creative districts, actually is. Look and see the masses of impoverished and fucked over people, the people who live less than paycheck to paycheck, the people who can't afford an ambulance, the people who have to work multiple shitty odd jobs just to get by, or risk getting kicked out by their epic liberal video game streamer landlord. These people don't even vote because they don't give a shit. This is the clay for the American socialist movement. Not the final, dying ambers of the fallen trade unionist titan, not the "woke" progressive students who can't handle being called a fag, not a bunch of RT reporters playing Lenin and not even the spontanious, unguided raw rage that we have seen in the recent riots. So, if you are an American socialist, or even a progressive, it is your political duty to go out and start building a movement from the bricks that the lord has provided you. Of course it won't be easy, yes, you might get gunned down by the feds like Newton was, but that is your best chance, bar the possibility of US just collapsing in on it self, to achieve American socialism.
