Gone are the days when if you read a story and thought it was BS, you ignored it and moved on. Or when a politician says something dumb, that's obviously untrue or a distortion, you just laughed and said "what an idiot".
Today, these things are "disinformation" and are "an attack on our democracy". This is a severe escalation, and I think what it's priming us all to do is reject Free Speech as a principle wholesale and replace it with an "official" narrative that is approved ahead of time (approved by who exactly, that remains to be seen).
All politicians spread "disinformation". That's the nature of politics: framing the facts of a story, or distorting them, to support your preferred narrative to get elected. Same goes for all partisan journalism, and the same goes for "mainstream" outlets that still have their own narrative they like to push for their own reasons. Somehow we're still so shell-shocked from 2016 that we've escalated every little bit of political tomfoolery to be a literal attack on the democratic institution itself. It's just bizarre.
