Since 1983, men who have sex with men have been prohibited from donating blood in the UK on the basis of purportedly elevated rates of HIV and other transfusion transmissible infections. This policy of deferral, known to many as the ‘gay blood ban’, has persisted in some form ever since and has been the subject of protest by individuals or groups termed blood donor activists. Utilising an array of theory from across science and technology studies (STS) and queer studies – situated at the nexus of a burgeoning queer STS – this thesis is a critical inquiry into UK blood donor activism. Drawing on archival research and 31 semi-structured interviews with blood donor activists in the UK as well as representatives of patient groups and the UK blood services, this research seeks to understand and critically interrogate the aims, motivations, and implications of the work of blood donor activists.

This thesis argues, first, that blood donor activism in the UK is motivated both by an opposition to blood donor deferral criteria as a technology of homophobia and a contingent framing of blood donation as an altruistic act, which marks out blood donors as good and happy citizens (an affective economy into which queer men seek inclusion). This thesis goes on to argue, however, that blood donor activism is a deeply homonormative political form with a politics that tends to centre ‘respectable’ (e.g. monogamous) gay men at the expense of other figures of risk, like sex workers or promiscuous queers. These politics, this thesis contends, are a product not merely of activist agencies but the epistemic (hetero)norms of the biomedical context within which lay activists seek to raise their credibility. This thesis suggests, therefore, that blood donor activism operates in pursuit of Pyrrhic victories governed by chilling structures that demand we seek alternative routes of political investment.
