I don't understand everything you just said but I probably agree?

Anyway deconstruction applies perfectly here because that's the core tactic underlying critical theory. It is a mental framework common to all liberalism, but taken to the extreme with the postmodern movement. You take a world view that was always known to be accepted and correct, and analyze it from the point of view of being just one alternative on a spectrum of multiple alternatives. Then when your ideology "wins", suddenly what was normal before becomes a fringe belief.
