This article studies the process of demonization, its consequences, and how social media contribute to the formalization of its axiology. The demonization of societies aims to create social subjects that fit into the idea of the “other” by exposing them to compulsory invisibility. This research’s main objective was to examine how demonization is used as a weapon of oppression to devalue specific individuals through the hashtag #StopIslam and Instagram’s role in this process. The methodology used for this purpose has consisted of an empirical and quantitative analysis of the most recent (1 January 2020–31 July 2020) posts on Instagram with #StopIslam, analyzing the images and the content. The study has determined how, through social media manipulation, erroneous ideas are transmitted that prevent the Islamic collective’s integration, especially in European countries. The conclusions will reflect hate speech and how the Islamic world’s demonization results in the Muslim community’s stigmatization, racism, and Islamophobia. Although there are different articles related to demonization and hate speech, there are not many scientific resources that explain these variables on Instagram and how it affects the inclusion of the Muslim community in Europe, significantly when the time spent on the Internet is growing.
