I am one of "them" and I care deeply about higher education which is why I am very sad that we could not achieve reform without resorting to measures such as threatening the international student admission process. I don't know anything about the people teaching the “truth” about the 2020 election in Oklahoma public schools but if this is happening I agree with you it is very wrong.
"If our schools have lost any edge, it’s since Trump came back to power."
I completely 100% disagree with this statement. My partner is an education at a University and remote learning had a huge negative impact on our schools and student outcomes. US academic achievement has been flat for decades despite spending and pupil rations going way up https://nces.ed.gov/pubs93/93442.pdf. Public schools in certain areas of the country are a complete failure for every student enrolled https://foxbaltimore.com/news/project-baltimore/at-13-baltim... (I choose an example of a left leaning area but obviously there are right leaning examples as well!)
Let me propose what I see as a couple of common sense reforms. Mandate the availability of pre-k nationwide starting at 4. Increase the school year from 180 days to 195 days by reducing the length of summer. If needed make this optional at first. Allow professors to fail students who have not learned the course material and make it illegal for the department to pressure professors to offer the students a way to pass the course.
