This chapter focuses on defectors to the far-left ideological spectrum of extremist milieus, for example, anti-fascist groups, anarchism, or communism. The case studies and storylines presented here belong to individuals who were active as right-wing extremists or even terrorists before they made the transition to the extreme left. In most cases, this transition is explained by frustrating and disillusioning experiences within the far-right environment, especiallydysfunctional and toxic relationships with other members.

Another set of motives belongs to the category of anti-establishment and ant-imperialism. Some switchers began feel that the struggle for a strong nation culminates in liberation from so-called imperialist capitalism.
