This chapter brings new insight to the study of young people’s activism in extreme right groups by considering their activism from a social movement theory perspective. It draws on the meta-ethnographic synthesis of findings of a cluster of ethnographic studies of radical right and patriotic movements conducted for the MYPLACE project, focusing on the emotional and affective dimensions of activism and on three case studies: the English Defence League (UK), Russian Run (Russia) and Torcida (Croatia). It considers the emotional pleasure derived from activism often expressed as going ‘wild’, feeling euphoric, or being overtaken by a physical ‘buzz’, as well as the reciprocal emotions that bind activists through feelings of solidarity and mutual support, expressed as feeling part of ‘one big family’.
