America's national anthem is terrible. "The Star-Spangled Banner," a poem about the War of 1812 set to an English drinking song, is almost impossible to sing, requiring a nearly two-octave range from start to finish. It's also racist. For many Americans, the conversation around "The Star-Spangled Banner" began in August, when San Francisco 49ers quarterback Colin Kaepernick refused to stand for the national anthem at the start of a game, in protest of police killings of unarmed black men.
