ABSTRACT
This chapter outlines the present conjuncture of online radicalisation and the consequences of the efforts to counter that, within the context of present concerns regarding the rise of terrorist violence. Contemporary anxieties regarding social media images, radicalisation, 'home-grown' terror and the ways in which attempts to counter them have, in turn, raised levels of insecurity among minorities of colour. As US and European governments have focused on stemming 'home-grown' Islamist political violence, the concept of radicalisation has become the master signifier of the late 'war on terror' and provided a new lens through which to view Muslim minorities. The affordances of the new media ecology, including global portals such as YouTube and Twitter and other multimedia platforms, user-generated content, on-line social networking, and the inexpensiveness and portability of new recording and editing hardware and software have allowed the uploading and wide dissemination of violent extremist content.
