The women’s marches were a phenomenal success and an important cultural moment. Most everybody came back uplifted and empowered. Many said they felt hopeful for the first time since Election Day. But these marches can never be an effective opposition to Donald Trump.

In the first place, this movement focuses on the wrong issues. Of course, many marchers came with broad anti-Trump agendas, but they were marching under the conventional structure in which the central issues were clear. As The Washington Post reported, they were “reproductive rights, equal pay, affordable health care, action on climate change.”

These are all important matters, and they tend to be voting issues for many upper-middle-class voters in university towns and coastal cities. But this is 2017. Ethnic populism is rising around the world. The crucial problems today concern the way technology and globalization are decimating jobs and tearing the social fabric; the way migration is redefining nation-states; the way the post-World War II order is increasingly being rejected as a means to keep the peace.

All the big things that were once taken for granted are now under assault: globalization, capitalism, adherence to the Constitution, the American-led global order. If you’re not engaging these issues first, you’re not going to be in the main arena of national life.
