Do not think of yourself as a warrior or imagine that the world is filled with enemies. It is too easy for the young soldier to declare war on the wrong target - it is surprisingly difficult to choose the right ones. Many intelligent and honest people find themselves on opposite sides of pitched battles. Frequently they even switch sides as they grow older, fighting ferociously for the position which their younger selves abhored.
Even if you win your war, you may find that the evils caused by the excess of some thing give way to new problems caused by its deficit.
Furthermore, the warrior is not an effective agent of change. The very nature of war is to divide people into allies and foes. An attack generates its own enemies, polarizing neutral bystanders into opposing camps.
Rather than be a warrior, be a builder. Tell a story that appeals to the universal values cherished by human hearts. Synthesize opposing viewpoints into a new worldview that unites former enemies. A fresh story has no enemies and it spreads without resistance, like a fire through dry grass.
In all the teachings of Jesus, he spared hardly a word for the pagan religion of Rome that his religion would replace. He was not on a mission to tear down the old world, but to build a new one. His story of hope, love, and deliverance appealed to Romans surrounded by a brutal and capricious reality. As a builder, he was far more effective than any warrior. The humane, egalitarian ethic introduced by Jesus is still a potent force in the world 2,000 years later.
That is why my I no longer think of my political activity in martial terms like a "warrior for liberty" or a "patriot". I grow tired of the eternal war between libertarian, socialist, progressive, and conservative. As I mature, I recognized the good motives and valid points of my former enemies. Instead of fighting old wars I'm focusing on building new viewpoints which can help people from all political ideologies create a better world.
My current attempt is Structuralism. I used to call it "Structural Libertarianism", but I realized that the structuralist ideas are useful for everyone, not just libertarians. By using the term "libertarian" I imported the old conflicts as if I'm so used to fighting that I forgot how to live in peacetime.
