The problem: You are feeling getting involved in a war.
War can be fought on several levels, it doesn't have to be physical war. It can be fought on economic level, on psychological level, in a discussion (see also How to Keep a Relationship at ThinkSimpleNow), by mobbing and so on. It hasn't to be plenty of soldiers running against another plenty of soldiers. War is already started in the small - when two people cannot live in peace next to each other. Although you in general do not want to fight or trigger a war you sometimes suddenly feel already within a war without either noticing how it happened. This can happen even although your philosophy is very far from starting wars.
The reason: War is mostly started during defense and defense is practiced because of fears.
Mostly a war is caused by defensive actions in the will to survive. While the will to stay living is a legitimate idea life is often not threatened. Defensive actions are already started when the idea comes up that something might happen that in the long run can threaten not only your life but also your resources and either your ideas. Defensive actions are often an exaggerated reaction to some others action interpreted as an attack or interpreted as the possible preparation for an attack.
In your daily life there can be many actions interpreted as an attack or as a threat by others without your notice and so you get fought and don't know why.
The solution: Stop actions that hurt others and don't act defensive where not necessary.
You need to improve your empathy ("try other ones shoes", imagine yourself in the situation of the other, listen with attention) to find out how you are hurting others. Pay attention not only to your actions, also to your words. Find out your fears - they might be completely exaggerated. Don't respond with defensive reactions where not necessary. Step back and look at the situation. Imagine a world war and think twice if it is really necessary to fight right here at the moment. Imagine there is war and nobody attends.
