While people use the term ‘mainstream’ on a regular basis, there has been relatively little discussion about what it actually means. Within far-right studies, attempts to define the mainstream often center around party politics and the impact of mainstream party strategies on the far right. While a useful starting point, this focus has led to more rigid conceptions which encourage particular normative assumptions about its identity. Through poststructuralist discourse theory, supported by insights from music studies and critical discourse studies, this article proposes a definition which accounts for its contingency and construction, challenging dominant narratives about its nature. These issues are crucial when we consider the relationship between the mainstream and far right because they encourage us to question their perceived relative positioning. By introducing the concepts of talking ‘with’ and ‘about’ the far right, this piece establishes the need for us to take the role of the mainstream in the mainstreaming of the far right seriously.
