Following the tumult of the Capitol Riot on January 6th, 2021 and the consequent social media ban of former U.S. President Donald J. Trump, debates around Internet governance have regained momentum. This has led to fervent contention on freedom of speech and social medias’ regulatory frameworks of content moderation. A key target of this moderation is extremist groups with a presence on social media, including the alt-right and jihadists. In particular, women of both groups have been playing an important role in the propagation of extremist ideologies online, frequently instrumentalising hyper-femininity to attract new followers. Because normative gender roles are exploited by violent groups, a gender analysis of how women propagate extremist ideologies is essential to effectively respond to online extremism. This article investigates similarities and differences of alt-right and jihadist women’s online presence and the role gender plays in shaping their respective propagandistic and recruitment methods on mainstream social media platforms.
