This entire article hinges on the premise that technology (mainly the internet) has magnified the differences and incompatibilities between people (mainly cultures/races).

I think this is wrong. Technology has only shown the pre-existing different and incompatiblies. Like those between your average coffee-sipping, liberty-believing, increasingly-athiest westerner to the middle eastern villager across the globe who's day job is to crush the skulls of living homosexuals and set them on fire.

Believe me now?
