The US history that Settlers covers is really useful especially when paired with Gerald Horne’s books and can help you build that material conception of whiteness and settlerism. I also appreciate that it breaks the orthodox view on the white American proletariat that they’re simply “tricked by racist lies” with no material interest in siding with the bourgeoisie. Labor aristocracy is a very useful concept in the Marxist conception of classes.

Honestly for white communists especially in America it’s a topic severly undereducated on despite how important it is for them to learn, so the more the better. I see that a lot of people aren’t aware of their settler colonial biases and it obfuscates praxis, tricks people into joining deeply settler orgs (ACP, CPUSA), and infects the platforms of more advanced orgs but with large settler bases like PSL and FRSO’s platform which includes Chicano Nationalism.

On top of Fanon and Settlers I would also suggest Marx at the Margins and EFF theorist Lwazi Lushaba’s decolonial lectures on youtube (his book too) on top of the aformentioned Gerald Horne’s books and just generally being more open to this applying settler colonialism as the principle contradiction – starting with native/black liberation and using dialectical materialism as the mode towards achieving it, reading texts even marxist critical texts from these perspectives, and seeing the failures of euro-american marxist theory and practice that have allowed it to be co-opted, declawed, and even perpetuate the “civilizing mission of progressive society” such as the case of the labor Zionists that carried out the nakba and the LaRouchites/MAGAcom grifters.
