Wall as a Metaphor

From the last presidential campaign, three slogans come to mind that embody the Trumpian call to fearmongering, isolationism and reductionism: “Make America Great Again” and “Lock Her Up” and “Build the Wall.”  While the latter two slogans are action-oriented, “Make America Great Again” is packed with cringe-worthy beliefs that encompass notions of free-loaders (both countries and persons of color), of resentment (of political correctness, multiculturalism, elites, government itself, globalism), and of rightness(finally, someone who will say out loud what I’ve believed all these years and act on it).
