I had a hard long think and I don't recall anyone making a plea for immigration in non-white countries. The Japanese wishing to keep their country filled with Japanese is not seen as a problem to be solved. The white farmers being marginalized in Zimbabwe and butchered in South Africa certainly didn't raise concern with the diversity aficionados either.

Well, I certainly don't have any hard data on this, so the point might be moot. When I think about it, you are probably right in saying that most people who argue for racial and cultural diversity are mostly thinking about western, white-majority countries. On the other hand I tend to think that they would also care for diversity in e.g. the Middle East or Japan, if one were to point the problem out to them. I might be wrong there though, since at least your experience seems to be different.
