This qualitative study investigates the contemporary landscape of lesbian, gay, bisexual, and transgender (LGBT) politics and activism, specifically the concept and identities of “straight allies.” Through in-depth interviews with 13 individuals who identify as straight allies, we explore how these heterosexuals engage in LGBT politics and activist cultures. We take a grounded theory approach to data analysis, through which the concept of “passive” and “active” activism emerges as a framework to understand these allies’ meaning-making practices, as well as how they negotiate the emotional, interpersonal, life-historical, and mass-mediated complexities of being straight allies when interacting with LGBT communities and engaging in pro-LGBT politics. We draw upon Thompson’s (2005) theory of ontological choreography to posit “identity choreography” as way to describe and make sense of the heterogeneous knowledges and experiences our participants use to constitute their straight ally identities and to evaluate others’ ally identities and activisms. Implications for future research on LGBT politics and straight allies, particularly in terms of education, attitude change, and activism, are discussed.
