As a liberal in California, my views on immigration actually hardened a bit after a recent trip to Japan. I appreciated that everything there was just so Japanese. No ethnic enclaves, no zones or industry that I could see dominated by non-Japanese people. I just loved the fact that I was in Japan and surrounded exclusively by Japanese culture. Made me think of what international travel must have been like 150 years ago, where visiting another country was like traveling to a different world.
I think according to the official regulations of modern US liberalism, this makes me slightly racist, and I'm supposed to be dismayed that Japan doesn't have more multiculturalism??
