I think most of us assume -often quite unconsciously- that we really are objective, and so become overly confident we can decide what is good bullshit and what is harmful bullshit.
IOW: Maybe sometimes, by true accidents of birth, we are simply in places where it's just not easy to hear folks yelling "Get off my foot!" because lots of people around us are yelling other things about how cool that same critter or thing is (the one causing unseen damage).
