An unprecedented cultural alliance is underway between the anti-trans strand of the radical feminist movement and a new brand of militant right-wing politics that takes issue with the idea that gender is a social and cultural construction. This so-called “anti-gender” movement—which also travels under names such as “gender-critical feminism”—has found immense international power and is especially active in Latin America, continental Europe, and Russia, with different but no less pernicious strains revitalizing longtime trans-exclusionary radical feminist (TERF) communities in England, Canada, the United States, and Australia. Contributors to this special issue consider what the global rise of trans-exclusionary politics and the envelopment of these politics into global right-wing movements might mean for changing understandings of transgender experience, science and medicine, and legal protections. Topics include the emergence of TERF rhetoric in evangelical Christianity, the anti-gender misappropriation of postcolonial thought in Europe, rhetorical and ideological similarities between TERFism and Zionism, and media treatment of J. K. Rowling’s hostility toward trans rights. Contributors. Serena Bassi, Mikey Elster, Jenny Madsen Evang, Gina Gwenffrewi, Greta LaFleur, Sophie Lewis, C.
