>In some ways anti-intellectuals create space for other intellectuals to get traction when opposing bad ideas promoted by establishment embraced intellectuals.
They really don't, though. At least, not a productive space. Intellectuals are quite capable of getting that traction on their own, and doing so on the basis of fact and evidence, rather than anger and a nihilistic mistrust of order and complexity.
You're putting a lot of effort into painting a heroic narrative of anti-intellectualism and of the harms of "the establishment" and intellectuals "over the ages," but that's a political stance, and one that assumes the anti-intellectuals are filling a necessary role in the ecosystem that intellectuals, themselves, cannot.
I put forth that there is no value to anti-intellectualism. Skepticism, yes. Questioning of authority? Yes. Opposing bad ideas? Yes. None of those are the particular domain of anti-intellectualism. Rather, those are all hallmarks of intellectualism.
The anti-intellectuals are the ones burning down the observatory so this never happens again. They're not helping.
