In this essay, I develop a pedagogical stance called the "free exercise of rhetoric" as a way to approach teaching and student writing at the intersection of LGBT and religious discourses. Through this stance, I work with students' personal commitments and build their rhetorical competence using a process that involves encountering uncommon arguments, valuing misreading, and embracing unpredictability. I suggest the free exercise of rhetoric as a pedagogical option for taking religion seriously as a topic and identity in writing classrooms, but one that does not start from students' personal experience with religion.
