ISBN978-1-107-11731-0. „"Persecution" in this study refers to violence or discrimination against members of a religious minority because of their religious affiliation. Persecution involves the most damaging expressions of prejudice against an out-group, going beyond verbal abuse and social avoidance.29 It refers to actions that are intended to deprive individuals of their political rights and force minorities to assimilate, leave, or live as second-class citizens. When these actions happen persistently over a period of time, and include large numbers of both perpetrators and victims, we may refer to a "campaign" of persecution that usually has the goal of excluding the targeted minority from the polity.”
