The Balkanisation of culture into silos of unreason means that the responses have not followed what might be loosely called the pre-digital rules of discourse. These rules assume that the purpose of public debate is to discern truth and that interlocutors on opposing sides—a reductionist bifurcation, because, in fact, there are many sides—engage in argument because they are interested in something higher than themselves: an ideal of truth, no matter how complicated, multifaceted and evolving. While in-group preferences and biases are inevitable, these exist within an overarching deliberative framework. This style of dialogue assumes the validity of a persuasive argument grounded in reason and evidence, even if—as Rowling does—it also utilises experience and feeling. By default, it assumes that civil conflict and opposition are essential devices in the pursuit of truth.
Three decades of postmodernism and ten years of Twitter have destroyed these conventions and, together with them, the shared norms by which we create and sustain social consensus. There is no grounding metanarrative, there are no binding norms of civil discourse
Brilliantly expressed. It puts into words why thread after thread involves GC women trying to use rational, persuasive argument grounded in reason and evidence - and meet nothing but 'you won't allow other opinions', mantras, abuse and other nonsense to no good purpose.
