This is an interesting article, but I’m sharing it specifically for this concluding comment:
To well-heeled Remainers who live away from cities – Sir Max lives in a country town in Berkshire, I believe – it may seem infra dig[*] to complain about changed communities, but it too often seems to be people who live in areas virtually untouched by mass immigration and multiculturalism who are the most evangelical about imposing it on others. See the Chipping Norton Remainer set.
Which is to an extent the case in Germany too.
* I had to look this up: according to Wiktionary it is a colloquialism meaning “beneath one’s dignity” (from Latin: infra dignitatem).
