From a queer-theoretical perspective this article investigates how religious norms are socially produced and maintained, and what consequences these norms have for people about to leave their religion. Previous studies have focused mainly on people who find ways to reconcile two often-conflicting positions. Other studies emphasise the eventual outcome of the conflict between sexuality and religiosity. The aim of this research is to generate a better understanding of former Muslims’ own knowledge and personal understanding of what it means to be or not to be a Muslim and discuss the process by which individuals resolve this conflict by leaving Islam.
