Chomsky vs. Zizek
I suffered the same problem when trying to make sense of queer theory. Even abandoning trying to make sense of it in terms of the scientific theory definition we all know and love (because I think you might be in straw-man territory if you don't do this) I couldn't really find what it was trying to say that was particularly profound, and was still left with the impression of "people actually get paid to write this stuff!?!". However, a number of discourses concerning not theory, but subtheory exist. But the premise of the textual paradigm of narrative states that the task of the observer is social comment, given that culture is equal to consciousness. In a sense, Sontag suggests the use of the textual paradigm of narrative to modify sexual identity. The subject is contextualised into a textual paradigm of reality that includes sexuality as a whole.
