A lot of people think that 'patriotism' amounts to wrapping yourself in the Union Jack and arselicking the royals. It is a very simplistic view that chimes with the prejudices of right-wing, nationalistic jackasses.
Patriotism should be about wanting the best for your country and its people, and that's a much more complex and nuanced thing.
Generally speaking, when politicians start trying to stir your emotions with abstracts you should be wary. Maybe even extremely wary. Emotions linked to politics or governance are a very dangerous thing.
