True Believers and the Great Replacement explores the responses of segments of Western cultures who fear that changes in the racial, religious, and ethnic makeup of society threaten their way of life. The Great Replacement Theory (that suggests that the traditional character of Western society is being undermined by outsiders) is discussed. Analysed with reference to the Critical Race Theory and the ‘Cancel Culture’ movement, the author examines the anxieties and reactions of those who feel alienated by a world of rapid and disorienting change. Drawing upon the thought of Eric Hoffer and Emile Durkheim, these responses are discussed in terms of the concepts of Anomie and the True Believer in innovative and effective ways. Based on this analysis, strategic responses are suggested. The volume will appeal to scholars and practitioners involved with issues of race and ethnicity, business and social and cultural analysis.
