This chapter brings fresh insight into how various forms of online communication contributes to growing anti-immigrant sentiments in contemporary society. It assesses the strategies of anti-immigration actors as well as every-day social media communication. The chapter discusses the affective dimension of social media use with an emphasis on how emotions and affect drive the circulation of anti-immigration discourse on internet. It demonstrates how anti-immigration and racist sentiments in public discourse are moulded through interactivity across media spaces, organised political activity and the mundane use of social media platforms by citizens. It argues that “uncivil” expressions on the internet push the boundaries of publicly acceptable speak and ultimately impact the broader public discourse on migration and migrants.
