The Women’s March on Washington began in a similarly ad-hoc manner. The protest sprang to life as an errant idea posted to Facebook, right after Trump won the presidency. The notion weathered controversy to evolve into something that, on Saturday, was funereal in purpose but decidedly celebratory in tone. The march, in pretty much every way including the most literal, opposed the inaugural ceremony that had taken place the day before. On the one hand, it protested President Trump. Its participants wore not designer clothes, but jeans and sneakers and—the unofficial uniform of the event—pink knit caps with ears meant to evoke, and synonymize, cats. It had, in place of somber ritual, a festival-like atmosphere. It featured, instead of pomp and circumstance, people spontaneously breaking into dance on a spontaneously formed dance floor.

And yet in many ways, the march was also extremely similar to the inauguration whose infrastructure it had co-opted, symbolically and otherwise, for its own purposes. The Women’s March on Washington shared a setting—the Capitol, the Mall, the erstwhile inaugural parade route—with the ceremonies of January 20. And, following an election in which the victor lost the popular vote, the protest seems to have bested the inauguration itself in terms of (physical) public turnout. During a time of extreme partisanship and division—a time in which the One America the now-former president once spoke of can seem an ever-more-distant possibility—the Women’s March on Washington played out as a kind of alternate-reality inauguration: not necessarily of Hillary Clinton, but of the ideas and ideals her candidacy represented. The demonstrations were an installation ceremony of a sort—not of a new president, but of the political resistance to him.

“I DO NOT ACCEPT THIS FILTHY ROTTEN SYSTEM,” read one sign, carried by Lauren Grace, 35, of Philadelphia. She got the quote from Dorothy Day. And she intended it, Grace explained to me, to protest “a system that sort of left me out.”

“We’re told that voting is a sacred right in this country,” Grace said. “But even though Hillary won the popular vote, she still lost. I feel pretty conflicted about a country where that could happen.”

The Women’s March on Washington was, to be sure, also a protest march in an extremely traditional vein: It featured leaders—celebrities, activists, celebrity activists—who gave speeches and offered performances on a stage with the Capitol in its background; its participants held signs, and chanted (“This-is-what-a-feminist-looks-like!,” “No-person-is-illegal!”), and commiserated. It was also traditional in that its participants were marching not for one specific thing, but for many related aspirations. Women’s reproductive rights. LGBTQ rights. Immigration rights. Feminism in general (“FEMALES ARE STRONG AS HELL,” one sign went, riffing off a famous feminist’s Netflix show). The environment (“CLIMATE CHANGE IS REAL,” “MAKE THE PLANET GREAT AGAIN”). Science (“Y’ALL NEED SCIENCE”). Facts (“MAKE AMERICA FACT-CHECK AGAIN”). Some signs argued for socialism. Some argued against plutocracy. Some argued for Kindness. Some pled for Peace. Some simply argued that America is Already Great.
