Martin, thank you for your proposal. Right away I was drawn to a couple of things. First, have you read "Why we are polarized" by Ezra Klein? You might enjoy reading his analysis. He also talks about the positives of polarization which are not talked about often - it is only in times of polarization that social progress happens. Times of depolarization are when oppression is not challenged.
Second, we need to acknowledge that there are simply some people who would never be open to what you are talking about. They are more concrete in their thinking and only have the capacity to see two sides - a right and wrong, us and them. What do we do with these folks? I don't know the answer to that.
Third, I love the idea of a third way - especially one focused not on debate and winning an argument, but rather being open to ideas and conversation. It focuses us on what we share in common as a starting point. We are no longer enemies or opponents to be defeated, but both trying to figure out how to work together to overcome a challenge by exploring ideas and potentials.
Thank you for adding this.
