Right, so we all know the arguments about monocultures in Trek, about how there's seemingly no diversity: one religion, one language, etc. Conversely, humanity has thousands of languages, regions, subcultures, & the like. Now, I'm a pretty big proponent of diversity my own self. My thoughts wandered as they're wont to do to some of the books I've read recently with neurolinguistics as main plot elements. Of course, I always start thinking about Snow Crash then, & I started wondering: what if monocultures are the norm? What if all these other species never had a Babel event that forced them to diverge & separate? Could this be why a large cooperative effort was never done before? That humanity--because of its diversity--was forced to learn how to deal with "other types" & that's what they brought to the party? We hear of the occasional "dissidents" who are usually political but only rarely cultural (the v'tosh ka'tur most readily come to mind); is this why there's such an acceptance problem?
