Fear and Loathing: How Demographic Change Affects Support for Christian Nationalism

Christian nationalism, the fusion of religious and national identities, has emerged as an important factor shaping public opinion on a range of issues. However, debates in the existing literature on the motivations behind support for Christian nationalism remain unresolved: Is Christian nationalism a response to secularization and/or a cover for discomfort with racial diversity and equality? Is Christian nationalism rooted in fear of social change, disgust about social change, or something else? We use an experiment embedded in a national survey of adults to isolate the effects of knowledge of both religious and racial demographic change among White Christians. Our analysis suggests that exposure to religious demographic change shifts support for Christian nationalism and perceptions of discrimination against Whites and Christians, but exposure to racial demographic change has limited impact. This effect is mediated by emotion—religious demographic change increases fear and disgust, which then influence support for Christian nationalism and perceptions of discrimination against Whites and Christians. Although our treatment suggesting exposure to racial demographic change had null effects, we note that racial attitudes do independently influence support for Christian nationalism and perceptions of discrimination against Whites and Christians.
