Anyone who has ever debated politics on the internet has probably seen a photograph of a wounded soldier shooting a pistol while being hauled across a muddy battlefield on another soldier’s back. It looks like it was taken on the front lines of World War II. Usually, it’s accompanied by a caption mocking liberals, such as this one authored by conservative firebrand Kambree Kawahine Kao this Memorial Day: “THIS is what bravery looks like. Not someone refusing to stand for the National Anthem.”
