Are you claiming that the ethnic composition of every country you listed hasn't changed dramatically over the last 25 years due to mass immigration from African and Middle Eastern countries?
These places have experienced continuous and significantly rapid linguistic and cultural change for centuries now. If anything high levels of literacy and experience of integrating minorities by force over the last centuries might be making this latest set of changes fairly gentle and manageable…
But my larger point is, that kind of diversity, while it has had some success in Europe, is a very different thing from the woke kind of diversity.
While French or German speakers in Switzerland works, It didn't work between Germany and France between you know 1810 and 1945. If you grow up in Germany and France this would not be a surprise.
Europe had lots of problems in the past (and usually people learn them in high school). You deny them just because of migration which both happen to be starting in the Germanys and France way earlier before the last 20 years (and also the discussions!). This also a known fact for people who care about these countries. And this is JUST Germany and France. This is not Europe.
If you curious about European or German history start the Wikipedia article , visit the countries instead of following American far right twitter accounts about migration.
"mental model to include more than just two ways of thinking, left vs. right." I do. I guess because you haven't mention which European country you are from and the typical demographic of HN, that you are American. And the American mind can not comprehend European history and links between various conflicts. So most peopöe can not put together into two bins of Politics like in the American election system.
