This is exactly why I fight these things. Another commentator explained it much better than me:

lazaroclapp - "There is a fairly long school of thought in ethics that posits that it's an important thing for most people to sacrifice self-interest in the name of justice, since it deters injustice. Basically, if most people respond to frivolous lawsuits by fighting them instead of settling or accepting unjust outcomes (within feasibility, of course), then engaging on frivolous lawsuits becomes unrewarding, and even unethical people stop doing so. The same goes for other kinds of bullying behavior."
