Yes, this is precisely that which they do not believe in. Plug your ears, bury your head in the sand, and whatever you do, do not use cause and effect, data, or evidence to backup your claims and positions. That is the platform upon which they stand.
The pitch is the usual anti-intellectual narrative: "How dare these people, with their fancy educations, look down on you and patronise you. Everyone's opinions are equally valuable. They're probably in it for the money."
It's been very organised, and both science and academia have completely failed to respond to it.
You can give science a pass because most scientists struggle to understand how craven politics and propaganda are.
Academia should have known better. Hannah Arendt described it far ahead of time. But somehow plain anti-authoritarianism became less sexy, and certainly less of a career move, than Continental Philosophy and Critical Theory, which have turned out to be largely impotent when faced with full-on fascism.
