ABSTRACT
This chapter provides an overview of the most important terms, concepts and frictions within the different argumentations and schools of thought. It examines where the radicalization and deradicalization discourse might have disconnected from the necessities of so called ‘front-line practitioners’ who are tasked with achieving success in working with individuals with different violent extremist and terrorist backgrounds, as well as with those vulnerable and under high risk of entering extremist movements. Most theories and especially the process models identifying phases and steps within the radicalization processes remain more or less deterministic in their attempts to identify biographical factors or root causes of radicalization. In addition to the question of the importance of ideology during enter and exit processes, the role of violence are key to understanding the various rifts within the terminological discourse. Quality standards could be the connecting bridge between the academic and practitioner discourse on terms and definitions.
