Jonathan Haidt 4: Can a divided America heal? (transcript)
Summary
This is about current America where Trump assumed the presidency. There's been on the left-right political divide since long ago though the big hopeless difference appeared this time. It's not just the feeling of disliking others but strongly disliking or disgusting them. It's usual to have an argument or a disagreement about something, but disgusting is different. It leads to a battle between good and evil, the feeling of disgusting increases, avoiding to do something together and dividing is deeper.  Moreover, people didn't vote for the candidate who they like. This is not the vote in favor of the motion but the vote for against though people don't realize it.
The reasons are that 1) people have a strong feeling that they want to have the same tribal, 2) by increasing it, each gruop is purified, and 3) the media or the fight provoke them more.
1) People have to realize them.  2) You don't think that you feel as other or you are disgusted with others. You have to have a new kind of empathy. 3) And then the opposite of disgust is love. Love can overcome the wall that is the feeling of disgusting.
You can't change the feeling of others though you can change your own feeling. The speaker tells us to stop seeing other people as your enemy, appreciating other, apologizing, and acknowledging other. This will be the way to heal.
