Critical thinking isn’t something that should only be applied if some invisible scale of awfulness tics past a certain [subjective] degree marker. It’s a difficult, tiring, important skill that must be applied—without free passes!—to the concepts and frameworks we live within and interact with. It isn’t enough to say, “at the end of the day homeless people have more tshirts and that is an unalloyed good”. To say that would not be completely honest. It is deliberately (albeit non-maliciously) avoiding labor that is necessary to inform our ethics as individuals and citizens, particularly if we are in a place of privilege.
Additionally, if we don’t start out from a framework that includes room for skepticism and grappling with moral complexity, we set ourselves up to progressively accept more and more problematic things until we are left with a terrible scenario that we are not ethically or intellectually equipped to combat. We drink the tiny poisons and eventually don’t notice the big ones.
