Yeah, yeah, I getcha.

Maybe I'm too harsh. I just feel like people read the same books over and over again and nobody's discovering anything new, you know? No new theoretical developments or info. Stuff like that.

Anyway, suggestions include Hinterland by Phil A. Neel and White Trash by Nancy Isenberg. Those are off the top of my head. Oh yeah, and An Ideological History of the Communist Party of China since that gives a lot of context to Mao Zedong's writings and the writings of his contemporaries. I guess you could also read Nikolai Bukharin's (not to be confused with Bakunin) work such as Historical Materialism: A System of Sociology. He was at odds with Stalin, as you may know, but he genuinely had some good writings.

Again, the books I just gave you were off the top of my head and I can try to find you some more that I've read or know about; they're meant to be "obscure" (since I believe that people shouldn't just read "required reading" or should at least try to mix it up a bit).

Also, I hear ya with the "new left" movement of the 60s/70s and beyond; nobody talks about it, but hell, it still affects us even today and in a very negative way.
