We humans are tribal creatures, and the sooner we face that fact, the better. No amount of cross-cultural outreach or kumbaya hand-holding is going to change human nature.
We all prefer to be around others who speak our language, share our values and understand our jokes. Human community is based upon similarities, not differences.
There's a reason why the Bible characterized the
Tower of Babel as a curse. Yet today's multiculturalists urge us to celebrate linguistic differences, as if not understanding one other were a good thing.
Diversity is a cultural fad among elites that will eventually go into the dustbin of history along with a lot of other failed ideas.
