Bit of a tangent, I remember reading a comment regarding old art's propensity towards showing past as nearly the same as present. Take medieval christian paintings - while depicting scenes from era way past and cultures far removed, they were typically depicted with then-current clothing, equipment, housing, etc. It's only during renaissance (hopefully not mixing that one up?) that people commonly understood past & other societies were significantly different from the present, with different customs, culture, technology, etc. Accompanying the awareness was ongoing research into how the past actually was; what were the possibilities and limitations; what was the culture and what drove people to certain choices, however misguided they may seem in the hindsight.
Through your comment I realize we are in process of losing the ability to clearly delineate the past, and to hold it as imperfect, but necessary, stepping stones to the present day. And perhaps also to run effective, objective research into the past, without feeling the urge to nudge it into direction of a preferred narrative.
where do you put your pent up hate without being hurtful? you attack the people who are perceived as hurtful first
You suggest we don't have true post-modernism, because it is not critical enough of the own operating moral framework. I counter that with: post-modernism is essentially only 'tried and tested' anti-modernism, but it doesn't come along as religious outrage like in the old times, but dressed in the form of moral outrage machines, that can be triggered by any form of non-conformist behaviour in any possible framework -- the frameworks have become interchangable, the operational mechanisms work like they always have.
It's not just that the border of fact and fiction has been dissolved. The question is not even considered relevant, because the statement isn't considered to be about truth in the first place.
"Everything can be interpreted in any possible framework" only in the sense that they will interpret your statement in the framework that makes it look the worst. Why will they do so? Because their interpretation of your statement is not about finding truth, but about their assertion of power. That is, these people are operating consistent with their philosophy.
