This essay considers the rapid uptick in anti-trans legislation that targets transgender girls and women as an occasion to critically interrogate the ways that gender is conceptualized and operationalized in political science (Murib 2022). I argue that the disciplinary tendency to view gender as a single-axis facet of identity that is static and rooted in biology needs to be reconsidered in light of two problems. First, collapsing biological sex and gender naturalizes the gender of non-trans women and men as static, normal, and self-evident; transgender people, in contrast, are locked into perpetual processes of gendering themselves against this biological baseline (Enke 2012). Second, and as a result of this limited view of gender, political scientists face difficulties anticipating, understanding, and addressing recent mobilizations invested in maintaining White, heterosexual, and reproductive families as the cornerstone of what it means to be a proper citizen (Alexander 1994).
