Rainbow Trap reveals how the fight for LGBTQ equalities in the UK is shaped - and constrained - by the classifications we encounter every day. Looking across six systems - the police and the recording of hate crimes; dating apps and digital desire; outness in the film and television industry; borders and LGBTQ asylum seekers; health and fitness activities; and DEI initiatives in the workplace - Rainbow Trap documents how inclusive interventions - such as new legislation, revamped diversity policies and tech fixes - have attempted to bring historically marginalized communities out of the shadows. Yet, as part of the bargain, LGBTQ people need to locate themselves in an ever-growing list of classifications, categories and labels to 'make sense' to the very systems they are seeking to access. This requirement to be classified catches LGBTQ communities in a rainbow trap. Because when we look beyond the welcoming veneer of inclusive interventions, we uncover sorting processes that determine what LGBTQ lives are valued and what queer futures are possible.
