The Focaultian mindset makes you twitchy, paranoid, and hostile.
We think of it as "of the Left", but there's also nothing to stop "the Right" from buying the idea that everything is just about Power. Then if you keep at that line of thought pretty soon you turn into a Nazi. Or at the very least, you will hear all claims from "the Left" about "care" or "empathy" with knowing cynicism.
And my perception is that these ideas have begun to spread subliminally throughout the culture, particularly among people who are younger or more educated. Everyone becomes more guarded. The social anxiety ramps up. The persona you see is increasingly a mask. The wall goes up a mile high and ten feet thick.
Have you ever met a friendly dog (stereotypically, perhaps, a golden retriever), that has never been mistreated? It will walk up to you wagging its tail; it is happy to meet you, because you are a person, and people, it has learned, are friendly and good.
Next: Have you met a skittish street-dog, the kind that shop-owners kick and curse as a cur, that walks around with nimble jumpy motions, with its tail between its legs?
The dog is a social animal, and is a model for humans. I observe that we humans are turning into the second, skittish type. You could call it a process of "de-domestication". We are all going feral. Uncivilized.
Life as a social animal is difficult to tolerate when your amygdala is constantly firing around others. But that's exactly the emotional effect of these ideas. And they are infecting everyone.
