Valentine argues that “transgender” has been adopted so rapidly in the contemporary United States because it clarifies a model of gender and sexuality that has been gaining traction within feminism, psychiatry, and mainstream gay and lesbian politics since the 1970s: a paradigm in which gender and sexuality are distinct arenas of human experience. This distinction and the identity categories based on it erase the experiences of some gender-variant people—particularly poor persons of color—who conceive of gender and sexuality in other terms. While recognizing the important advances transgender has facilitated, Valentine argues that a broad vision of social justice must include, simultaneously, an attentiveness to the politics of language and a recognition of how social theoretical models and broader political economies are embedded in the day-to-day politics of identity.
