There's no doubt bad faith actors are using it for their own purposes and their intended target is the latter kind of person. The lack of self awareness is in my opinion quite common. There's simply too much to deal with for the average individual on a daily basis to allow ourselves a type of introspection that can clarify who we are and how we act. We are vulnerable to catchy phrases as it is simply too exhausting to analyze every bit of information coming our way, so we accept shallow definitions, we accept a path of superficial righteousness and we accept the paper thin sweetness thrown our way. Only to have it all crumble at a deeper look, taste or thought and leave us helpless.
People are dumb. Intelligence is an exercise. And we have to specialize if we want to achieve something. That means we have flaws to be exploited. And they very much are, in every way.
So I try not to blame the lack of self awareness. Because we all experience it in different ways, of different things. Not knowing is okay. But how many of us can accept that about ourselves or about others? Not many, else the world would be a happier place.
