Using a combination of computational and qualitative content analysis, my research focuses on ideological cross-pollination between the online manosphere and the alt-right, exploring thematic similarities in user-generated discourse on extremist platforms. In addition to hypothesising the implications of these findings regarding the nature of the on and offline self – and how these factor into supremacist radicalisation – I also aim to provide empirical support for the conceptual treatment of these loosely connected networks of interest groups as biotopes forming self-sustaining and ever-evolving virtual supremacist ecosystems that, while somewhat ideologically distinct, overlap and influence one another as in the natural environment.
