The Eurabia conspiracy theory narrates a supposed plot to transform the European continent into an Islamic society through the destruction of white Christian civilization, brought about by the secret alliance between Muslims and the domestic elites of Europe. It surrounds the radical notion that the incorporation of elements of the Muslim world into Western society will mean its total collapse, meaning that white Christian civilization will then become a 'colony of Islam'. From this, the present paper aims to semiotically analyse messages from a popular white supremacist Telegram group, with the application of digital humanities methodologies (Natural Language Processing), seeking discursive practices and language patterns (signs, texts, codes) that can potentially assist in the codification of religious meanings and in the formation of Islamophobic ideological clusters on Telegram, pointing to how these patterns fit inside the wider process of radicalization. It is possible to argue that there is a structural tendency for religious fundamentalists to uphold conspiracy theories, which is reflected in their dichotomic thinking style aimed at making sense of societal events by providing oversimplified explanations, following the notion that any other ways of interpretation are evil or wrong. The Eurabia conspiracy theory describes a perfect past - when Europe was only populated with white Christians - which is subsequently followed by a 'fall from paradise' - caused by multicultural policies/immigration and the perceived rise of Islam - ending in a redemption story - plans for making Europe return to its supposed religious (and ethnic) roots. Generally, radicalization processes and religious conspiracy theories are both fundamentally related to meaning-making mechanisms that provide cognitive consonance by introducing a narrative from which one may drive purpose and, thus, organize a cohesive and meaningful way to interpret this complex and conflicting reality.
