Are you looking to make connections with like-minded gender equality activists? Check out New Wave Young Boston Feminists. From their about page:
New Wave is a group that incorporates the myriad perspectives of our members to build a radically-welcoming feminist community. This isn’t our grandmothers’ Feminism – we draw on the great progress of previous generations while forging ahead and creating our own path. As a diverse group of Feminists, Womanists, Gender Studies students, professionals, and other folks with an interest in gender equality, we welcome ALL voices, Queer or straight, cis or trans, all genders and all backgrounds.
While you’re at Meetup, you might also visit the pages for Boston Pro-choice Supporters and the Boston NOW Chapter.
