STEM is an exclusionary space for queer and trans* students of color (QTSOCs). A critical site of justice-oriented transformation to enhance support for QTSOCs is mathematics education, which has significant impacts on access to STEM majors and positive identities in the sciences. This article proposes a set of rights for QTSOCs as STEM learners to guide pedagogy that affirms intersectionality of their experiences in and beyond mathematics classrooms. QTSOCs in STEM have the rights to: (i) feel confused and receive support; (ii) take risks in participation and identity expression; and (iii) have affirming representation of identity in knowledge production. To illustrate how these rights are denied and embraced through STEM pedagogy, I present 2 narrative cases from my research study about QTSOCs' intersectionality of STEM experiences where mathematics played a central role. I conclude with implications for practice to cultivate rehumanizing STEM educational opportunities that QTSOCs deserve.
