So from what I understand, the anti-oedipus is what is going to save everybody, or rather "redeem mankind", from the ideals and future nihilism to come. But Deleuze differs from Nietzsche's form of antinihilist discussion based on the fact that Nietzsche went mad, and "madness is a radical break from power in the form of a disconnection". The concept of how power works through the connection to everything is very interesting. Some statements in this essay are somewhat appalling. Deleuze/Guattari literally seem to be connecting everything to everything.
I thought this quote from the Anti-Oedipus was very postmodern:
Even revolutionary groups deal gingerly with the fascisizing elements we all carry deep within us, and yet they often possess a rarely analyzed but overriding group 'superego' that leads them to state, much like Nietzsche's man of ressentiment, that the other is evil (the Fascist! the Capitalist! the Communist!), and hence that they themselves are good (xvi).
