There seems to be a lot of opinions floating around, and PSL members seem particularly vocal though I’ve heard some rumblings of SA from leadership.
Because of the constant risk of CIA infiltration I know all orgs need to be justifiably paranoid, though I’ve no idea if any are completely CIA captured. If any are I’d assume it’s CPUSA because of their prominence.
At first glance the RCA seems interesting (Edit: misread something earlier, fuck them Trots) but I don’t know enough about their OpSec yet. That’s why this seems a really valuable question to bring to the community. In theory I’d want to join one I can join under an alias in case of infiltration.
Find the one that most closely aligns with your ideological tendency and jump if to see if the water’s fine. Make sure you make whatever meetings there are, listen first for a few weeks to before diving into whatever party culture you’re entering. Nobody likes a self-styled vanguard of the masses walking in day one and trying to command their way to revolution. See what skills you can learn, be that organizing and running meetings, taking efficient notes, learning a bit of digital art to make agitprop, working on your journalistic writing for whatever party web-paper you’re writing for, etc. If nothing else, spend whatever time in whatever party you join productively. Also don’t be a wrecker shitheel that steals shit from your by then former party.
Also we’re more worried about the FBI domestically. If you’re a traveling delegate, then you’d be more worried about the DHS-ICE.
