The presidential election of 2016 generated a wave of explicitly gendered protest activism. The post-inauguration Women’s Marches in D.C. and around the country are estimated to have involved more than one in every 100 people in the United States and likely represent the largest single-day demonstration in American history. The marches were organized and dominated by women who reclaimed and reworked gender stereotypes with pink hats and feminist slogans. Other organizations which emerged to challenge the Trump administration often were founded by women and/or had an overwhelmingly female membership base. For example, women made up about 70% of members of groups associated with the anti-Trump Indivisible Project. Daily Action, a service that encourages users to call members of Congress, reported that women accounted for 80% of its users after 2016. Women in general are more likely than men to say they have participated in a political event or protest since the election. The future may well be female: The presidential election of 2016 inspired heightened interest in engaging in protest among (Democratic) adolescent girls.
