all heavily supposedly “progressive intellectual” examples that you very carefully avoided
It's weird that you accuse me of cherry-picking when that's what you're doing. There are a ton of pedagogical theories, movements, and ideologies that could all be described as "liberal" and they all compete and at times were supported by various people of various political persuasions.
Were most of those people liberal? Yes. But most people involved in education are liberal. The people who toppled the anti-phonics movement—not the state politicians that railed against it for being "politically correct," the people who actually persuaded educators to drop it—were primarily liberals! I live in a very conservative state that, until recently, was all in on the whole language approach. This had more to do with the successful lobbying efforts of certain textbook companies than any true ideological preference by the state legislature.
How can you honestly assess a situation when you're so stuck in this mindset where everything is left or right?
You also avoided addressing “fascist” Florida and Louisiana significantly advancing minority achievement in k-12 while California falls FAR behind despite going all-in on CT.
I have no interest in that, I don't know enough about the statistics you're citing to make an informed comment about it, and it's not related to phonics vs. whole language despite your best efforts to rope them together. Your weird ideas about "Critical Theory" and somehow suggesting that California schools are pedagogically influenced by Foucault's postmodernism demonstrates you are clearly out of your depth here. It sounds like you read a lot of Quillette but don't understand half of what you're reading.
I can discuss at length my gripes with the "theory" movement in higher education and how detrimental it has been. That has very little, if anything, to do with our K-12 problems. Our K-12 problems primarily stem from funding issues that are exacerbated by charter schools, disparate school districts, attempts to "punish" poor performing schools, "teaching to the test," and allowing religious schools to exist. There are also major cultural issues.
