He has similar platform to what you will find in many other european countries. Le Pen in France. AFD in Germany. Dansk folkeparti in Denmark.

How does EU "fight" that? By playing for the long run: freedom of movement, cultural exchange, freedom of business. In the long term this leads to a more liberal society, regardless of counter movements.

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.

Does spain is included in your non-nationalistic western europe? A state where old fascist are still in charge in justice, police and army? Who cheeringly cracked down on catalonia who dared to organize a referendum on independence?

Or, well france. Who declared as a first move of presidency of EU to make french the standard working language of the EU?

Nationalism isn't restricted to eastern europe.

Which would likely be done by every country that respects rule of law and equal rights of its citizens.

I supose by rule of law, you don't mean:

Aside from that, the UK showed with scotland, how it can be done dealing with political issues, without involving the police. Because that is just in tradition of the fascist way.

Parts of states do not simply arrange independence referendums without approval from the central government. This would be “cracked down” in every single country on earth. It may well be that Catalonia deserve independence but it’s not exactly surprising or authoritarian of a central government to stop such attempts. Scotland doesn’t arrange an IndyRef without getting a nod from London.

But how could they have proceed legaly, when the central government made it clear, they never respect their right of self determination?

By trying to move that opinion. It might take three or ten generations but it’s hard to see an independence movement go faster without violence.

UK says hi!

By conservative nationalism I mean something that is much further removed from liberal democracy than Nigel Farage or even LePen. It’s not about economic conservatism, closed borders and populism in immigration matters. I mean (extremely) socially conservative.
