This is the grave of Martin Luther King, Jr.
Martin Luther King is a man who gave one speech in his life. In that speech he talked about dreams in such a vague way that he actually meant to give support to whatever conservative talking point happens to be in vogue today. King had no interest in economic justice, opposing the war in Vietnam, building an inclusive society, desegregating housing and schools except in the most formal legal way, or fighting against white supremacy. Nope, he was just a man with a vague dream.
Martin Luther King, Jr and Coretta Scott King are buried at the Martin Luther King, Jr. National Historic Site, Atlanta, Georgia.
