A condensed explanation of “American exceptionalism” from Wikipedia:

“American exceptionalism is an ideology that rests on the notion the country is inherently different from that of other nations, stemming from its emergence from the American Revolution, becoming what one political scientist called “the first new nation” and developing a uniquely American ideology, “Americanism”, based on liberty, equality before the law, individual responsibility, republicanism, representative democracy, and laissez-faire economics. It’s also the idea that America has a unique mission to transform the world. In his Gettysburg address, President Abraham Lincoln said Americans have a duty to ensure, “government of the people, by the people, for the people, shall not perish from the earth.” Finally, it’s the idea that America’s history and its mission give it a superiority over other nations.”

Trump is a walking, talking refutation of American exceptionalism. At this stage in our nation’s history, how can anyone feel a sense of superiority?
