Every single one with a Roma population, likely.

Anecdotally, I remember having discussions with Danish family in the 90s, about racially-related issues in America, and in the shape that they took, I recognized how woefully unprepared they were to really look at their own racist attitudes (e.g. vis a vis Turks and immigration). When I returned in 2019, and had a chat with a gentleman supervising a number of different immigrants on some sort of work-integration program... well, I wasn't much impressed with his expressed attitude towards the workers.

France? The discourse around islam is insane there, and you have an almost neo-nazi party like the FN getting 30%+ of the votes regularly there. There is no shame in talking about forced expulsion of legitimate immigrants there too( "Remigration" ).

Any of them with nearly as much ethnic diversity as the United States.

France. Big time.
