This paper examines the role of nationalism in Polish soccer fans’ protests in resistance to LGBTQ+ equal rights. Drawing on data from semistructured interviews with 22 nationalist activists, namely ideological leaders of hard-core soccer supporters’ community, who shape the ultras’ nationalist discourse, the study explores their rationalizations behind anti-LGBTQ+ demonstrations. By recognizing nationalism as an ideological background, our study goes beyond theories of masculinity, a dominating way of explaining discrimination against sexual minorities in sports (fandom) to date, and it identifies a wider set of rationalizations, conceptualized in two broader models: (1) naturalist rationalizations, and (2) the counter-counterhegemonic rationalizations, which include three more specific themes—(2a) anti-antihegemonic masculinity (2b) anti-Western and (2c) anti-leftist.
