In modernity, the image was a representation of reality, while in postmodernity, reality is a representation of the image of reality. Thus rationality is replaced with emotionality, as reality is sought to recreate the image, which is always selective and subjective. This perception is inevitably at odds with a perception that strives for an objective truth.
By the very nature of this emotional reality, postmodernity denies itself with the facade of rationality, all the while voiding formerly rational concepts of their actual rational content, and replacing them with emotionality. This allows to understand how the root of all social and political division is not left vs right or conservative vs liberal, but modern vs post-modern ergo rational vs emotional, but with an emotional side that pretends to be rational. It is a fight for the prerogative of truth being in either rationality or emotionality.
I'm revising it right now, writing a more complete foreword, going further into the image issue and mentioning the sociopolitical modern-postmodern spectrum.
