I agree with what others have said about exercising caution when studying enemy material. In the past, I thought I was too smart to get tripped up by reading obviously false enemy nonsense, but their garbage is still dangerous. Not to say that one should never study controversial things, but be careful. If you're in doubt, it's best to stick with reading the clergy's critique of things like Communism, rather than reading leftist materials themselves. If you use discretion, reading material by people who were mostly woken up (but not fully Satanic) can also be useful, but still use caution, as even smart White Nationalists may have some subconscious enemy influence. George Lincoln Rockwell and Dr. William Pierce have done some very good work debunking leftists, although Rockwell does pander to Xians in some of his work (although he personally hated Xianity, as he stated in a private letter to Savitri Devi, I believe HP Mageson mentioned this.)
Right now, the popular thing among leftist academics (at least in America) seems to me to be the "critical race theory", feminism, "privilege" theories, etc. Leftists here seem to be less interested in traditional, economics-oriented Marxism and prefer the more explicitly chaotic, anti-White "deconstruction" theories. Most of the notable writers in these fields are clearly Jewish. Tim Wise, Noel Ignatiev, Susan Sontag, Betty Friedan, Gloria Steinem, etc. Their writing is some of the most disgusting, dishonest garbage in existence.
Jewish leftists used to be more subtle in their anti-White rhetoric and even tried to appeal to working-class Whites. Howard Zinn, a Jewish Marxist, mentioned how most Whites who were brought to America were economically dispossessed, not privileged elites. Eugene Genovese mentioned the same thing (Genovese supposedly repudiated his Marxism later in life, I'm not sure if this was genuine or if he just became a neocon, like many Marxists did.)
