People always descried the postmodern with all its irony, cynicism, distrust, moral relativism, self-referentiality, and cultural iconoclasm.... apparently post-factual is the new paradigm. Perhaps all postmodern did was instil such a deep distrust and skepticism towards every bit of information we process, that factuality no longer matters in the slightest, we now believe whatever we find most compelling, fuck its factuality.
And to think people thought post-modernism would lead to a new sort of sincerity... though when one thinks about it... post-factuality and new-sincerity do go hand-in-hand to some extent, since the presence of sincerity is much more valued now than factuality. Sincerity means one can be absolutely cavalier with the truth with pretty much no consequence.
