Judith Butler, the ground-breaking philosopher whose work has redefined how we think about gender and sexuality, confronts the attacks on gender that have become central to right-wing movements today. Global networks have formed ‘anti-gender ideology movements’ dedicated to circulating a fantasy that gender is a dangerous threat to families, local cultures, civilization – and even ‘man’ himself. Inflamed by the rhetoric of public figures, this movement has sought to abolish reproductive justice, undermine protections against violence, and strip trans and queer people of their rights. But what, exactly, is so disturbing about gender? In this vital, courageous book, Butler carefully examines how ‘gender’ has become a phantasm for emerging authoritarian regimes, fascist formations and transexclusionary feminists, and the concrete ways in which this phantasm works. Operating in tandem with deceptive accounts of critical race theory and xenophobic panics about migration, the anti-gender movement demonizes struggles for equality and leaves millions of people vulnerable to subjugation. An essential intervention into one of the most fraught issues of our moment, Who's Afraid of Gender? is a bold call to make a broad coalition with all those who struggle for equality and fight injustice. Imagining new possibilities for both freedom and solidarity, Butler offers us an essentially hopeful work that is both timely and timeless.
