This article offers a comparative thematic analysis of two datasets: the online writings of Autistic self-advocates on navigating neurotypical programs (emic dataset), and discussions on autism within the most widely circulated undergraduate Adapted Physical Activity (etic dataset). Our 3 themes describe some of the most significant ways that APA textbooks differed from the teachings of Autistic self-advocates: 1) "Writing in Categorical Imperatives," 2) "Problematizing and Pathologizing Autism and Autistic Characteristics," and 3) "Promoting ABA and Autism Speaks." We end with a discussion of how these findings demonstrate a dissonance not only between APA and Autistic knowledges, but also between APA textbook approaches to Autism and APA's stated core values, including dignity, choice, self-determination, and self-advocacy.
