This book focuses on how 'cult rhetoric' affects our perceptions of new religious movements (NRMs). 'Cult' Rhetoric in the 21st Century explores contemporary understandings of the term 'cult' by bringing together a range of scholars from multiple disciplines, including sociology, anthropology, psychology, and religious studies. Ranging from the 'Cult of Trump' and 'Cult of COVID', to the campaigns of mass media, contemporary 'cult' rhetoric has become hybridised and is common vernacular for everyday people. The contributors explore these issues by analysing how NRMs have developed over the past decades and deconstructing the language we use to describe these movements.This book provides a renewed discussion of 'new religious movements', whilst also considering recent approaches toward a nuanced study of contemporary religion. Topics explored include online religions, political 'cults', 'apostate' testimony and the current 'othered' position of the study of minority religions.
