Thinking about the word “fractured”, what turns merely holding different views and letting them inform each other in a friendly and fair competition into a fracture? I suspect it comes down to fear and insecurity. When we distrust the other, being afraid that their gain is our loss and their agenda may hurt our (psychological, financial, etc.) security, we start acting erratically. Fear manifests itself as anger and contempt. We are not relaxed and watch every word they say for signs of pushing their agenda. We are torn between considering it beneath ourselves to spend effort arguing with them, and being unable to stay silent. We don’t know when are they themselves and when they represent their group. You can truly enjoy friendship (and indeed love) if you are secure on some fundamental level, and I suspect it is a hard precondition. I don’t know where I’m going with this. Maybe we should look into being more secure and relaxed? Pay heaps more attention to mental health, our own and our society’s? Learn to play non-zero-sum infinite games? Release some part of us from having to fight for survival if we are lucky to enjoy highest ever standards of living?
