Background: Autistic adults frequently experience social stigma, which may be compounded by additional marginalized identities such as race, gender, and sexual orientation. Black autistic adults, in particular, may face unique challenges at the intersection of racial bias and autism stigma. However, the experiences of autistic people with intersecting marginalized identities remain underexplored in research, contributing to a limited understanding of stigma’s impact across diverse communities. Methods: We used qualitative methods to explore how intersecting identities shape autistic adults’ experiences of stigma and marginalization, with an emphasis on Black autistic adults. In total, 32 autistic adults (16 Black and 16 White) completed a semi-structured interview regarding their social experiences. Participants shared recent stories of peer exclusion, acceptance, discrimination, and support that they had experienced, as well as their feelings surrounding these events. We recorded and transcribed these interviews and used an inductive, or data-driven, approach to thematic analysis to identify salient themes in the data. Results: We generated three intersectional themes, which encompassed the unique impact of stigma on those with intersecting identities. Specifically, these themes included: (1) identity-based discrimination shaped by race, gender, and LGBTQ+ status; (2) challenges in obtaining and processing an autism diagnosis; and (3) difficulties navigating personal identity, particularly among Black autistic participants. While autistic adults broadly reported stigma experiences, Black participants often described layered forms of exclusion related to both their race and autistic traits. Across racial groups, women and LGBTQ+ participants also reported distinct forms of marginalization and erasure. Conclusion: These findings highlight how autism stigma intersects with other marginalized identities to shape social experiences. Black autistic adults, along with autistic women and LGBTQ+ autistic people, may encounter compounded barriers to acceptance, identity development, and belonging. These results underscore the need for more inclusive research and supports that attend to the diversity of autistic experiences.
