FRSO seems good on most things, but supports "upholding past treaties" with native Americans, which is somewhat of a red flag. PSL seems good but I've heard claims that they're not that good on the settler colonial issue either and lack proper democratic centralist structure. I don't know much about the WWP, but their 15 point programm doesn't mention landback at all. I know next to nothing about the other socialist parties/orgs on the US, so I can't give my opinion on them
Not aware of FRSO chapters endorsing lib politicians, but I'm also not well acquainted with the org outside my own chapter.
Yeah a good comrade joined their local chapter recently, found that out, and then dipped lol
I can only say that there is none of that shit going on where I am
