On Saturday, a constellation of woman-centered, anti-Trump protest lit up across all seven continents. (A group on an expedition ship in Antarctica adopted the unofficial slogan “Penguins for Peace.”) At the center of the action was the Women’s March on Washington, which drew an estimated half a million participants. There were men and women of all origins and orientations, a teeming parade of pink hats and protest signs that brightened against a pale silver fog blanketing the sky. There were sensible moms and crust punks, bros in Patagonia and toddlers on shoulders. A group of Gen Xers from Pittsburgh kept yelling, “Go Steelers!” A great-grandmother leaned on a walker, ambling gamely down the National Mall with clouds of cotton in her ears.
