Who is The Patriot from The Four Loves and what is their importance?

Lewis talks at length about patriotism in the context of having love of one's country, though he says the word "patriot" may be extended to indicate love of family, regiment, class, etc. Lewis says that person who is stirred to patriotism by a couple of beers and a rousing tune played by a brass band is at one end of the spectrum, while the extreme patriot at the other may be exhibiting unhealthy levels of devotion. The danger, according to Lewis, is in setting the stage for leaders to feed on that devotion to the point of wickedness and for individuals to lose sight of God because of their preoccupation with country.
