Between just trying to just absorb more theory, browsing the DSA vs. PSL vs. Local Org vs. Whatever struggle sessions, and listening to some recent KushVlogs from Christman (call me a lib, I know), I see a recurring theme of the lack of a cohesive, united leftist movement in America. To my (probably incorrect) mind, this seems like a non-insignificant hurdle to actually gaining real leftist power in the US and has made me curious to see what kind of path people see through this uncertainty. To me, it almost feels like a collapse/balkanization of America might be the strongest possibility but I'm just throwing ideas at a wall.
If lack of a unified movement is your concern, join the IWW and the DSA. They're the most cohesive national level left wing groups, and you'll find radicals in both. They're also both multi issue, so you'll be able to peruse whatever you think is most likely to pull the lever.
That said, I think we'll need to see movement crossover on a large scale if we want to seize power. Think about the dockworkers striking against the iraq war. Think about the cops out of AFL movement. Think about the red house defense by BLM and Antiascists under the stop the sweeps banner. Think about chicago teachers striking to get jrotc out of their schools.
We need to generalize those alliances so that the working class fights as one for co liberation in a deliberate, interdependent way where leadership comes from within the class and takes the form of many, many people.
So if you're in an org, make connections with orgs that don't usually cross communicate. I know anarchists and abolitionists often agree, but don't work together. Make those connections. SAlt and DSA are doing a lot of the same electoral work. Make those connections. If you want a unified left, unify it.
