This paper centers two complementary theoretical approaches to advance the debate about transgender women’s inclusion in elite women’s sports – namely, non-ideal theory and cultural studies. In doing so, the paper highlights divisions between ideal theory and non-ideal theory, normative internalism in sports and normative externalism in sports, and essentialist views of sports compared to non-essentialist views of sports. The paper’s main agenda is to show the value of applying non-ideal theory, externalism, and non-essentialism to the discourse over transgender inclusion.
