Imagine you have an instinct for expressing and recognizing in others agree/disagree/uninterested, which I suppose in its most simple form can be gestured with a shake of the head or nod, or turning away, or/and spoke or written. Consider the yes/no we’re so familar with to be as instinctive as turning and looking in the direction of someone calling your name.
Given all the things that humans might be said to have native potentials for recognizing, some for example like dead/alive, near/far away, in pain/pain free, anxious/relaxed (to name just a few that many other animals would possess), how much of a stretch would it be for humans, conscious apparently with an advanced mental tool box, to juggle the seeming contradiction of strong group norms and too powerful respect for the idea that they should not to be imposed on any member of the moral community.
If you had to bring together the most basic of instincts (or native abilities) to work on that apparent contradiction what would they be, and how would resolving them/it influence your moral and political views.
