The second case study of the book has a dual objective. The first relates to the content of our investigation and in particular our understanding of violent radicalisation and extremism in the virtual (online) space. In constructing preventative models against violent extremism and radicalisation, first we must understand their nuances. This chapter helps to develop this knowledge further by focusing on the variables of virtual vs real space, as well as age. The second objective relates to the methodology of our investigation and of any investigation into the causes and solutions of social justice abuses. This refers to the youth-led methodology, an innovative participatory approach to creating evidence-based social policy. The chapter draws lessons from a survey that was designed, implemented, and analysed by a team of ten young researchers, and which attracted 697 young respondents from across Europe. The description of this methodological tool and the reflexive analysis of its successes and limitations lead to a wider argument according to which youth-led approaches would constitute a timely contribution to European social justice policy and prevention against violent radicalisation, extremism and the hate narratives that are gradually being normalised through both formal and informal structures of governance.
