Once upon a time, sons of European nobles set off on road trips to hack, skewer, and drive people of other faiths from "holy lands." We call those travels crusades. Many "holy warriors" embarked with the same gleaming eyes and clueless grins now seen on kids of American elites joining the Peace Corp for somewhat vague do-goodery. We call these travels "noble causes." Commoners, like me, usually travel for unspiritual reasons like finding a job, scoring a babe, or escaping the law.
