What does it mean to celebrate America on its 250th anniversary? The Trump administration’s festivities — from the U.F.C. fight on the White House lawn to the Great American State Fair — have centered American glory and greatness. What has been missing are the Americans who fought to move America closer to its promises. They had to love a country — or at least believe in a country — that often failed them. How did they do it? Beneath that is a deep question for anyone who loves a country, or even loves another person: How do you love something in its wholeness, amid its imperfections and failures? One person who is thinking deeply about how to do this is Bryan Stevenson. He’s a civil rights lawyer and the founder of the Equal Justice Initiative, which is based in Montgomery, Ala. E.J.I. has created a series of museums and sites in Montgomery that aim to examine America’s history of enslavement, racial violence and segregation, while also uplifting and honoring the people who endured these systems and fought to upend them. The sites are remarkable to witness, as I found out when I visited Montgomery, and they hold America’s manifold truths in tension with one another — all its horror and beauty, tragedy and triumph, inhumanity and humanity. I asked Stevenson how he’s thinking about America’s 250th birthday — and what work the country has left to fulfill its vision of liberty and equality for all.
