Given the tendency of Populist Radical Right (PRR) parties to form anti-LGBTQ+ claims, this thesis aims to understand how a PRR party operating in a context characterized by progressive values relates to LGBTQ+ topics in their political messages on social media. A single case study of the Sweden Democrats (SD) – an example of a PRR party operating in such a context – was conducted. Idea analysis, which included the concepts of homonationalism and heteroactivism, was performed on 44 posts published during the year following the 2022 election on the social media platform X by politicians representing the SD in the national parliament. The results show that the SD pursued a homonationalist discourse in that they advocated LGBTQ+ rights to oppose Islam in general and Muslim integration in Sweden in particular. However, when the SD solely focused on the Swedish domestic context, LGBTQ+ rights were not promoted, but rather heteronormativity was favored above non-normative relationships, gender identities, and gender expressions. Thus, the results suggest that the SD took part in heteroactivism. Moreover, while the SD avoided outspoken homophobic statements, transphobic ideas were evident. Hence, the SD adapted to the Swedish context by performing a balancing act where they weighed the expression of heteronormative ideals against the potential loss of acceptance from a public supporting LGBTQ+ rights. Altogether, these results contribute to research on PRR parties operating in contexts characterized by progressive values as well as research on the SD concerning LGBTQ+ topics.
