This article examines how the language and logics of the Christian Right in South Korea contributed to the propagation of anti-asylum sentiment during the Yemeni refugee crisis in 2018. By analyzing the Christian Right's historical origins in anti-communism and its moral opposition to anti-discrimination law, it shows how the anti-asylum movement owed much of its support to a conservative Protestant view of international refugee rights, seen through the lens of minority rights at home. Ultimately, it argues that overlaps between religious and national ideologies of anti-communism activate conservative Protestant linkages between moral boundaries and border security.
