Hence people falling back to “I don’t care” as a defense mechanism. The world is too big, and there’s too much awful happening, to emotionally invest in all of it. Not and stay sane. It’s so much easier to narrow focus to your own life and pursuits, and let everything else be what it is.

And so we get these useless platitudes, because “I don’t care about that” can be both true and socially unacceptable at the same time.
