In 2014, Kate Livingston created a quirky Halloween costume for her 12-week-old son. It featured a black, sleeved onesie. And a white silken collar. And a pair of large, plastic-rimmed glasses. Livingston snapped a picture of the cosplaying infant—he provided the cool scowl—and then added a caption, in blunt all-caps, to the photo she took: “I DISSENT.” Ruth Baby Ginsburg was born.
