The most contentious thing about Foucault is his notion that we are controlled by our discourses. (I don’t find this contentious at all. I believe it be true.)
It is up to each individual to be aware of the many discourses active in the world at any given time.
Awareness can "defang" a discourse.
We have numerous lenses. If we are aware of the idea that we are viewing the world through lenses, this gives us the chance to spot the discourses operating on us.
