We’re still a European country.

On which criteria? Since Margaret Thatcher said she wanted her money back, and even more since Brexit, UK is geographically in Europe, just like Switzerland or Ukraine, but definitely hasn't the "European Mindset", UK is its own thing as they've always wanted to be.

What is the "European mindset"? that of Norway, Ireland, Greece, Poland.....?

The one that created the European Union

The European Union is not Europe.

If you look at my list you see it includes both EU and non-Eu countries. IMO the non-EU country's mindset is more like that of its nearest neighbours who are in the EU. Ireland is far more like the UK than it is like any of the EU countries mentioned.

I would be interested to hear a definition of that "mindset" that includes all EU countries that excludes the UK, Norway. Switzerland, Iceland etc.

Yes but there is an English breakfast and a Continental breakfast.
