If a country needs to overly emphasise an ideal, that’s usually because that ideal doesn’t apply in that country (“Land of the free”, “Democratic people’s republic of …”).
If a person needs to subscribe to patriotism, it’s usually because they have never accomplished anything better in their life than being born in a specific place.

Are you proud that air exists? I have better things to be proud of than a country.
