The point is, none of this develops in a vacuum. The ability to empathize is only learned by upbringing, assuming you don't have a defect in your brain like autistics do. Our cultures as they exist today aren't as they are because we naturally tolerate people that look different from us. It's taken centuries of science and government intervention for us to have reach the climate we live in today.
I've already provided evidence that if a person isn't nurtured, they can develop into a person that doesn't recognize other human beings, can't recognize their own face, and doesn't understand the concept there is a world outside of their's. I don't get, what you don't get.
Frustrating, because I have to go to work.
