I've read travelogues from the 17th-19th centuries, and in a lot of them, all of the countries are described like Japan. "Look at these weirdos, they insist on ______!" A tourist going from France to Italy would be constantly amazed, offended and puzzled. No longer.
It's a weird thought for me to have. I'm not a conservative; I view xenophobia, fear of change, and cultural/economic death grips by an older generation as negatives. But it feels like most of the world that doesn't have those things is increasingly homogeneous, in a way that's also uncomfortable to see.
