Instead, try thinking about this as you look at that map. Culturally, the military in this country is overwhelmingly "on the right". And the region of the country except these few tiny isolated locations, represent the home of the most heavily armed civilian population on the planet. So when the liberals finally decide to bend the rules one lawyer too far, and try to actually "ban guns" or one of their other 'final solution' style progressive policies, how long exactly do you imagine it will take for a citizenry who no longer consents to be ruled by these people, to thin them out?
The Mexican border wall that Trump promised isn't a bad idea. But if we really want to make America great again, we should be building it around these tiny progressive islands.
