The Fundamental Sources Of PC / SJ / Progressive Madness

There are different ways of trying to organize and understand the madness, but my very long-standing view is that this way of doing so captures something true and important:

     What's the fundamental source of madness on the PC left?

          A lack of regard for truth (or, equivalently: facts).

   To say that x is "politically correct" is to indicate that x is not actually correct. I.e. not really true. I.e. not true. Political correctness--which is, IMO, largely indistinguishable from contemporary "progressivism" (but absolutely distinct from by-God liberalism...)--is, in essence, the view that accordance with left-wing political orthodoxy should be substituted for accordance with evidence. (As an actual matter of fact, 'PC' is a term for left-wing insanity of this type; but it might as well mean any such insanity. There's obviously plenty of it on the right, as well...though there does seem to be some sense in which this particular kind of madness is more acute on the left...)

   And a lack of respect for truth/facts goes hand-in-hand with the view that thinking so makes it so...which might itself be represented as the fundamental problem...though I think it's a slightly subordinate one. Almost no one thinks that believing that x actually makes x true. Mostly people who want to believe such a thing just let it all be a kind of muddle, so that they avoid focusing too clearly on the difference between:
          S's belief that p makes p true
          and
          p is neither true nor false, but S believes that p
     This craziness is mixed up with rape crisis hysteria, one aspect of which is the idea that you were raped if you think you were raped, and that your environment is hostile if you think it is. It's also obviously at the very heart of this strange contemporary view that your "identity" is whatever you think it is--where this is now commonly said to be the case with respect to "gender," sexuality and "ethnicity" (Though mostly the left is drawing the line at race, in order to rule out Rachel Dolezal / transracialism cases. That decision on their part was more-or-less arbitrary, so it could easily change in a year or two.) It's the crazy heart of transgender ideology, as well as views according to which indigenous beliefs constitute actual knowledge.
   Liberals like to think that a major difference between them and conservatives is that they respect truth and evidence--and, so, science--whereas conservatives don't. But that just isn't true. The left is at least as bad as the right when it comes to subordinating truth to orthodoxy. The left just focuses on cases in which conservative preferences tend to conflict with science and liberal preferences tend to accord with it--e.g. in the cases of climate change and creationism. When leftist ideas conflict with the evidence, the left is every bit as fast to side with orthodoxy: IQ is pseudoscientific, Jenner is a woman, GMOs are dangerous, race is "socially constructed."
   Eh, that's enough of that for now.
   Somebody's getting crazier and crazier...it's either me or everybody else.
   Inclusive 'or'.
