The fiercest battles over gender today aren’t just about identity or womanhood—but about punishment, fear, and control. The twenty-first century “gender wars” have been driven by a powerful and seductive narrative: that safety can be secured through exclusion, surveillance, and the policing of difference. These punitive logics have gained momentum across the political spectrum, fueling an anti-trans backlash and distorting the meaning of safety itself. Unsafe is a clear-eyed and decisive challenge to the toxic ideas at the heart of this backlash. With patient rigour, Lamble exposes how carceral approaches to safety fail to address root causes of harm, ultimately deepening social divisions and legitimising new forms of violence and control. Drawing on feminist and queer traditions as well as their experience organizing against prisons and policing, Lamble makes a principled case for a different vision: one where safety is not built on punishment but on collective care, radical solidarity, and transformative justice.
