Same reason I might care about the ethnic makeup of Japan. I like some aspects of Japanese culture and I would hate to see it disappear due to cultural homogenization.

I don't want to guess too wildly, but I suspect you also support the rights of indigenous peoples to practice their culture in the former British colonies like Canada or Australia? Why is the idea of wiping out British culture in 2025 OK, but the historical destruction of indigenous cultures - as in Canada's residential schools - treated as a grave injustice similar to genocide?

All cultures evolve. Most of them disappear. They leave influencew behind as they meld. Any modern culture will be recorded very precisely.

What is this non-sequitur? White people in Britain still have the right to practice their culture as they see fit. You can eat all the beans on toast you want, even if your neighbor is eating curry.

From the same article.

I can totally understand this point btw. What I don't understand is

> London is no longer the city I was infatuated with in the late '90s and early 2000s. Chiefly because it's no longer full of native Brits.

Can you tell me how has London changed for the worse from '90s and early 2000s to today for a Dane to lose interest in it ?

> I don't want to guess too wildly.

Please don't. I am a brown dude from a Third World country. I do follow DHH's blog.

I don't think you should care about the ethnic makeup of Japan.
