This article examines whether mainstream political parties have adopted prejudiced rhetoric from the far right and how such shifts influence public perceptions of anti-prejudice norms. Drawing on the mainstream accommodation literature and the literature on the effects of elite rhetoric on social norms respectively, I argue mainstream adoption of far right rhetoric weakens anti-prejudice norms in the eyes of citizens. Empirically, I document the rise in mainstream hostile rhetoric toward immigrants and minorities using a novel source of data. I also show that such rhetoric is associated with social norms against supporting the far right, and with expressed prejudice in society. Additionally, I examine the causal effect of mainstream prejudiced rhetoric on norm perceptions through two preregistered survey experiments in Germany and Denmark (n = 7,200). Overall, I find that mainstream prejudiced rhetoric weakens anti-prejudice norm to a considerable extent in the case of Germany, with more muted effects in Denmark. .
