Unlike most other countries, our citizens hail from virtually every nation on earth. They share neither ancestry nor race nor ethnicity nor religion. When we speak of American culture in the singular, we cannot be talking about the culture of any particular group. We must mean, instead, the civic culture of principles, institutions and history that we can share—the only culture that can bind us together as one nation. Every form of ethno-nationalism is un-American.
America’s reason for being is spelled out in the preamble to the Constitution, the charter of our civic life: to “form a more perfect union, establish justice, insure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity.”
