What I got out of it is the concept from psychology -> distinguishing self from other. You want to make sure your perceptions are real and not projections, that your reactions are appropriate and not transference. The only way to avoid those things is to recognize what it coming from within yourself. I can see how that sounds stupid or absurd to a lot of people, however it's like the blub paradox - if you're looking up the abstraction ladder all you see is a bunch of strange words and jargon.

I can see fairly clearly, and some of that is due to psychoanalysis that nearly killed me. Another very closely related psych truism is that there are hidden influences lurking below your conscious perception, and often another level below that. Most people reject that notion (obviously, they can't see it) and some get angry (that's often a defense against finding that which is hidden).

When you see the dumpster fire here, it's the dumpster in their heads that they're not even aware of manifesting in the comments.
