If there ever comes a time when AfD creates a board to “review” Supreme Court justices, or moves to remove “foreign influence” on media in Germany and so on - then the same discussion will return there. The difference is that conservative nationalism can’t get that type of foothold in Western Europe and the mistake was to include countries in the EU that even had a risk of having a nationalist majority. We should have “tiers” of membership with a legal/political inner union of liberal states that can have a common foreign policy, and a wider less tightly coupled trade Union with the EEA that doesn’t necessarily need to agree on such things.
