Because otherwise we wouldn't feel the need to drill it to our kids in school.

Like potty training, obviously if it wasn't for parents teaching basic human stuff our kids would just shit and piss everywhere casually.

We tend to overestimate how much substance we're teaching to other humans, while what we are often doing is passing down "form". And "form" is very important because that's what our social instinct forces us to do, to create differences between us (with the right manners) and them (with the wrong manners)

> Because otherwise we wouldn't feel the need to drill it to our kids in school.

That's pure tautology. It's also the case that no professional agrees with you that these emotions are "intrinsic."

> We tend to overestimate how much substance we're teaching to other humans

What are you basing these assertions on? Personal feeling or are you drawing from some resource that I could also study, because so far, I can't find anything that backs up your points.
