John Scalzi explains why he doesn't write a lot of political posts anymore:
[S]o much political messaging these days, particularly on the right, is so performative that engaging with it is also performative, and a furtherance in distributing the original performative messaging. The political right in the United States understands that, inasmuch as it currently lacks a coherent political strategy other than will to power, it must keep its followers forever afraid, and its opponents forever on the defensive — spending their energy responding rather than doing anything else. So: outrage at trans people and black people and librarians and candies and anything else that will keep the outrage cycle going on for another 24 hours.
And, you know, I… just don’t want to. I’d like to say that it’s because I don’t have time, but I have the time, as much as I ever have with regard to this site. I just don’t have the inclination. So much of it is fucking trivial, for one — the individual incidents, to clarify, not the overall intent to strip everyone but white dudes of their rights — and all of it is “I said or did something shitty, now you have to respond, so I can play my next card.” Engaging in that level of rhetorical dishonesty for anything more than the length of a tweet feels icky, and even engaging in it for that long is fast losing its appeal.
As usual, he (the professional writer) puts in words what I've also felt. And he's completely correct, of course; you can't engage on policy when your opponent isn't serious.
