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
FRSO also views the US as having internal countries being (imperialised? Sorry my phrasing is bad,) the Black Belt south and Aztlán, which they advocate self determination for
Advocate self-determination for, not separatism.
Thank you
Yes, but self-determination can encompass political autonomy
