Autistic people that hold other marginalized identities, such as being LGBTQ+, may be especially vulnerable to stigmatization and discrimination, and their experiences may be understood through the lens of intersectionality. This study aimed to explore the differences in the experiences of stigmatization and discrimination between LGBTQ+ and non-LGBTQ+ autistic people. Eighty-seven autistic adults, 41 of whom were LGBTQ+, responded to a survey that measured stigma centrality and salience, stigma consciousness, experiences of everyday discrimination, and awareness of intersectional stigmatization. Results showed that LGBTQ+ autistic participants expected to be stigmatized and discriminated against more often and saw their autism, gender, and sexuality as more important to their identity than non- LGBTQ+ autistic participants. The frequency of everyday discrimination did not differ between LGBTQ+ and non-LGBTQ+ autistic respondents. The findings suggest that further research is needed to fully understand the intersection of autism and LGBTQ+ identities.
