This book in religious studies uses a Malaysian apostasy case study as a platform to investigate and discuss the broader radicalisation of apostates on social networking sites. It provides new insights into the emerging phenomenon of how social media tools are harnessed to promote faith and beliefs systems, specifically looking at the Malay view of apostasy from Islam. Employing sociocultural theory and theoretical concepts to analyse the discursive behaviour of a Malaysian apostate on a social networking site, the study unpacks how digital storytelling and rhetorical strategies can influence readers, culturally and socially, and contribute to identity construction in relation to politicised viewpoints. The analysis of the discourse surrounding apostasy in Malaysia enables parallels to be drawn to such discourses in other parts of the world, raising discussions on the connections between inflammatory online rhetoric and social problems, such as recruitment to terrorism, involvement in gangs or the use of addictive substances. This book is of particular interest to scholars and students considering the intersection of critical discourse analysis and religious studies. It is of interest to sociolinguists and psychologists interested in online media.
