Walk closer, though, and you'll find the spaces between. The names without dates of marriage. The men buried beside other men. The soldiers whose pictures stayed in their footlockers because home wasn't yet a place where they could be themselves. Walk to Section 66 of Arlington National Cemetery, and you'll find the headstone of Air Force Technical Sergeant Leonard Matlovich - discharged in 1975 for the unspeakable crime of telling the truth - which reads, in his own words: "When I was in the military, they gave me a medal for killing two men and a discharge for loving one."
