First read this this answer for the grammatical reference: Why is the subject placed in the end of this sentence?
Then try to follow along with your own sentence: B -> A (reverse)
it turns us against
the very entity
that holds the capacity to address society’s most pressing problems and on which democracy and freedom depend, our own government.
Compare with this simple sentence:
A --> B (ordinary)
His bad manners
threw [subject A]
me off immediately. [adjunct B]
B --> A (reverse)
There was something in his behaviour that threw me off immediately, [ adjunct B]
his bad manners. [subject A]
*Notice the subject of something in the first part of the sentence.
It does the same job as the word entity in your example.
In English grammar, a delayed subject is a subject that appears at (or
near) the end of a sentence, after the main verb. In such cases, the
vacant subject position at the beginning is usually filled with a
dummy word, such as it, there, or here.
It comes from this article: What Are Delayed Subjects in English Grammar? You can see if that's of any use to you.
