Abstract
In 2016, amid an epidemic of police shootings of African Americans, the celebrated NFL quarterback Colin Kaepernick began a series of quiet protests on the field, refusing to stand during the US national anthem. By "taking a knee," Kaepernick bravely joined a long tradition of American athletes making powerful political statements. This time, however, Kaepernick's simple act spread like wildfire throughout American society, becoming the preeminent symbol of resistance to America's persistent racial inequality.
