Ursula K. Le Guin said this quote
“ War as a moral metaphor is limited, limiting, and dangerous. By reducing the choices of action to “a war against” whatever-it-is, you divide the world into Me or Us (good) and Them or It (bad) and reduce the ethical complexity and moral richness of our life to Yes/No, On/Off. This is puerile, misleading, and degrading. In stories, it evades any solution but violence and offers the reader mere infantile reassurance. All too often the heroes of such fantasies behave exactly as the villains do, acting with mindless violence, but the hero is on the “right” side and therefore will win. Right makes might. ”
