Why are there two sides to a fight? If you investigate something from a scientific point of view, you may look at many different variables. You may come up with a pareto distribution based on your observations. There's nothing particularly natural about having two sides. I think there are two sides because of the fight itself. There may be many points of view, but people choose the side closest to their point of view. After the fighting starts, all the nuance about those points of view disappears. After the fighting starts, it is disloyal to acknowledge any weakness in the arguments or proposals of your own side. After the fighting starts, the two main camps will subsume any smaller groups. ---- I think it's interesting to think about times when there were more than two sides: China during and shortly after WWII - think about Japan vs China and KMT vs Communists. During the Japanese invasion and occupation, the Chinese forces mainly cooperated, or at least tried to appear cooperative. Once the pressure of that fight ended, the Chinese groups were free to fight each other --- Another: US vs Communism until the end of the Cold War and then Red vs Blue. --- Do you have any examples?
