Honestly, we kind of have this now. Emotions have divided the country. Racism is driven by hatred and anger. Environmentalism is based on fear and hope to save to planet. War is based on greed and dissatisfaction. Religion is based on fear, hope, desire. Celebrations are based on joy and pride.
Anger, fear, sadness, joy, etc. it all shapes our viewpoints, morals, and how we treat others.
