Social media has indisputably become a place of debate and social change over the last few years when it comes to feminism and heteronormativity. Based on a corpus of Twitter and Instagram data in English, French and German, my research focuses on multimodal discourses about heterosexuality and more specifically on metadiscourses that provide commentary on internet content that displays stereotypical heterosexuality and/or heteronormativity. Using the tools of multimodal critical discourse analysis, such as revealing implicit ideologies at play and using visual analysis, the goal of my project is to look at how certain communities of social media users question and redefine heterosexuality and heteronormativity and how this can give us insight into current heterosexual norms and how the evolution of heteronormativity is perceived.
