>"Maybe we can think about techniques to create empathy among strangers."

It's all about abolishing hierarchical leadership, and the "one-to-many" dynamic. People who foment tribalism like Trump, for instance, are only effective in a mediated environment in which they are immune to any criticism and can pontificate from on high. In a one on one social situation, his behavior and attitude would be laughed at and ostracized because the vast majority of people are generally good and wish to be peaceful. But when they are able to atomize individuals and speak directly to them, the power of their rhetoric is irresistible, because it appeals directly to the person's identity. That's why Trump supporters will follow him off a cliff. He is them. His thoughts are their thoughts. And the basic human survival instinct kicks in when anyone attacks something you identify with so intimately.
