 If gender becomes a matter of bodily style and performance, as this model suggests, then there is no necessary link between gender and any particular bodily shape. The alignment between anatomical shape and gendered performance is itself just a norm. Furthermore this norm, along with others governing gendered performance, is open to destabilization and change. For Butler same sex practices are one way of destabilizing the normative links of gender and heterosexuality. Various trans performances, in a parallel way, challenge the link of anatomical shape and gender. The trans community, problematised by sexual difference theory, therefore comes to occupy a central position for Butler. They are pivotal to the process of “queering” by means of which gender binaries, established by normalizing practices, are to be undermined and unravelled. So, for example, the television documentary, Pregnant Man by McDonald (2008), featuring a pregnant man who is referred to as a man and presented as a regular guy, works to undermine our binaries. What remains problematic about this, however, is that the effect of performance is unpredictable. Drag, for example, can support or dislodge gendered stereotypes and we cannot always sort out which any instance will produce. This make possibilities for reflective agency difficult to negotiate (McNay 2000).
