Two CIA guys in Oslo, having lutefisk for lunch and the waiter comes with a cheese plate with some fruits:
CIA spook 1: "Have some cheese, it's brown in Norway"
((CIA spook 2)): "Yes, the cheese has to be brown because no one is brown here"
TV series from 2018, not too far the 2015 benchmark. The whole plot is absurd, with an "alt" right candidate for the Bundestag paying for a terrorist attack with State Department funds, which was thwarted by the American embassador, among other insanities.
Culture is a product of people, and people are a product of culture, in an ever-consuming ouroboros. Add in globalized media, and it spreads like wildfire.
But likewise, a cure can spread just as efficiently. Just a few years of "no gibs unless you're married, cohabitating, and in good social, personal, and legal standing" would turn the entire community Amish. Problem is, right now, there's a LOT of money and a lot more of power on the line to keep them down.
