In this article, the author explores the challenges for sexual citizenship campaigns as same-sex marriage emerges as a touchstone for progressive politics in Australia and beyond. Analysing popular media and public debate, she argues that there is much to be learned from recent critiques of liberal and colonial feminisms. Jasbir Puar argues that the ‘woman question’ is currently being supplemented or supplanted by the ‘gay question’ as a marker of a nation’s modernity, democracy and ‘civilization’. In the context of widespread support for marriage equality, an urgent challenge is how to respond to an emerging ‘homonationalism’ in public culture which positions the West on ‘the right side of history’ in contrast to homophobic Islam, and a liberal version of gay rights which obscures ongoing discrimination and injustice.
