If you are actually looking for some eyewitness accounts, Jordan Peterson has many podcasts where he interviews specific people that have experienced the ideological takeover themselves, including:

* Yeonmi Park: https://www.youtube.com/watch?v=8yqa-SdJtT4

* Dr. Rima Azar: https://www.youtube.com/watch?v=cIw8mH7ZpFY

* Bret Weinstein: https://www.youtube.com/watch?v=2O_gW4VWZ5c

He has also interviewed one person who lost his job fighting the takeover in high school:

* Paul Rossi: https://www.youtube.com/watch?v=ysQBegyQP8A

He's also interviewed a self-identified liberal and former employee of New York Times that witnessed the takeover at the Times. Starting at minute 8 the conversation diverges into talking about her experience at University.

* Bari Weiss: https://www.youtube.com/watch?v=tFTA9MJZ4KY&t=12s

Bari Weiss says it herself in this podcast, loosely quoted since I don't remember it exactly: If you as a liberal can't see the danger in what is happening, then you have your blinders on.

I would say the same holds true of people who can't see the takeover in education, which is already mostly complete.

Edit: I found the Bari Weiss quote at 43:06: "I have to be honest. At this point, if one can't see the way that this language has been hijacked and used as a kind of trojan horse strategy to smuggle in a hardened, zero-sum identity politics view of the world, to smuggle in a view of the world in which we have collective guilt or collective innocence literally based on the circumstances of our birth, that smuggle in a deeply anti-capitalist position, to smuggle in essentially a leftist illiberalism, then, I'm sorry. You have blinders on! The evidence is so overwhelming at this point.... I think it's because admitting that's true, is extremely psychologically scary, and socially scary, if you are a liberal."
