The causes of discrimination are complex, diverse, and crosscutting. This is further complicated by the fact that the multiple causes of government religious discrimination (GRD) manifest differently in different settings. This chapter examines levels of GRD in an eclectic group of states: Christian-Orthodox-majority states, Buddhist-majority states, and Communist states. While this may seem to be an odd grouping of states, there are at least four commonalities between them. First, each of these groupings contains relatively few states. Second, GRD is distinctly common in these states and high in many of them, though the reasons for this differs across groupings. Third, some form of ideology and government religion policy both play a strong role in causing GRD in these states, but the many other causes of GRD also play an important role. Fourth, as I discuss later, GRD against Christians is particularly high in these countries. Orthodox-majority states focus this GRD on Christian denominations they consider nonindigenous, mostly North American protestant denominations. The Buddhist-majority and Communist states seems more generally hostile to Christians, most of whom they also consider nonindigenous and in some cases a threat to the state.
