In the academic year of 2017–18, one of the editors of this volume convened a course on gender and sexuality at a UK university. The course elicited overwhelmingly positive feedback from students. However, following examinations an invigilator expressed concern, communicated via management, with the language some students used in their answers. Specifically, the invigilator took issue with students employing the acronym ‘TERF’ (Trans-Exclusionary Radical Feminist) to criticise a range of ideological positions, because they considered the acronym a misogynist slur. The course convenor’s line manager subsequently asked whether the term was used within teaching materials.
