I just realized that when I say:

“People don’t care about…”

What I really mean is:

“I don’t care about…”

We tend to project. I should say, I tend to project.

I think it’s still valid though. I would argue that in most cases when this sentence is said, it’s providing advice to someone.

When you project and say “people don’t care about,” it is in fact “I don’t care about.” However it is simply that your mental model is sufficiently advanced to embody on behalf of a collective what people don’t care about, and save time for someone to discover that.

Haha Indeed 
And most of the time it is a direct reaction to another person who does care about. 
Which makes the sentence even more absurd. 
We could see it as an often akward rhetoric technic (related to hyperbole).

the lens we judge others through is often just a mirror
