America is in rough shape. Not financially, as the Dow Jones Industrial Average topped 40,000 for the first time last week, and unemployment is the lowest it’s been in more than half a century. Crime is down and income inequality recently decreased for the first time in more than 15 years. We are in rough shape because we are more fragmented and polarized then we have been since the 1960s, if not the 1860s.

We argue among ourselves over everything from immigration to Taylor Swift amid a social and news media landscape that feeds us anger in exchange for advertising dollars. But there is one thing we should all be able to agree on: better people than us sacrificed their lives so that we can even have the arguments we are having.

Next week marks the 80th anniversary of D-Day, where 2,501 Americans died on the beaches of Normandy. It is worth taking some time this Memorial Day to not just honor their sacrifice but to recommit ourselves to the values of democracy, freedom, and justice that they died defending. And to find common ground with each other wherever we can to make sure our disagreements never rise to a level where we are required to make that ultimate sacrifice.
