This paper explains the logic for using the concept of gender-related violence (GRV) as a broad category that problematises homophobia, transphobia and the policing of gender norms and the gender binary, as well as gender-based violence—understood as primarily violence against women and girls (VAWG). It then evaluates the utility of this concept and its capacity to introduce theoretical refinement to the study of gendered violence, by reviewing its reception within a large international feminist project on gendered violence in the lives of children and young people. The aim of this study was to improve knowledge and understanding of forms of violence and discrimination among practitioners who have everyday contact with general populations of children and young people. It sought to improve their ability to identify and challenge sexist, sexualising, homophobic or transphobic language or behaviour, and their knowledge of how and when to refer children and young people to appropriate support. The paper reports my view of the contribution that the concept of gender-related violence made in each of the four project sites: Ireland, Italy, Spain and the UK. The findings are mixed: in Spain and the UK the concept seemed helpful, but in Italy and Ireland it was initially expected to be helpful but, in practice, a conceptualisation closer to gender-based violence plus homophobia was employed. It is tentatively concluded that where LGBTQIA+ rights were well-established as well as the problematisation of VAWG, this framework was successful, but that it was less successful in more heteronormative sites where homophobia was less problematised. It is suggested that, as a concept, GRV can make a valuable intervention in sites like the former.
