This dissertation is about trans joy: the feeling of happiness and comfort that comes from embodying a gender identity that is protected, supported, and celebrated by others. I situate this joy in the context of the regulatory efforts of binary gender, which is itself an effect of European colonialism. My dissertation starts from the increasingly rampant demonization and criminalization of trans bodies and turns to the strategies used by trans people to realize an existence characterized by joy. Drawing on examples of embodied rhetorical practices such as pregnancy, management of body hair, and style of dress, I demonstrate material ways trans people disrupt the marginalizing mechanism that is the gender binary—at the same time subverting colonial gender ideologies. The dissertation argues that bodies are an ideal rhetorical tool for trans worldmaking, a project that creates the conditions necessary for the protection, support, and celebration of trans identities and experiences. Each case study is presented as a model for trans worldmaking that can be taken up and reproduced, circulating the subversive potential of trans bodies. I argue that not only is binary gender a colonial effect, but also that trans rhetoric has the potential to subvert and remake gender to be a category that enables joy rather than regulation. Trans worldmaking is one project of an embodied rhetoric that is especially powerful when it plays out visibly on a wide-reaching stage: when audiences resonate with a non-conforming embodied gender, they see that their own identity is possible—that, in fact, there is a world in which their identity can (and should) be protected, supported, and celebrated.
