Public rhetoric refers to discourse both within a group of people and between groups, often centering on the process by which individual or group discourse seeks membership in the larger public discourse. Public rhetoric can also involve rhetoric being used within the general populace to foster social change and encourage agency on behalf of the participants of public rhetoric. The collective discourse between rhetoricians and the general populace is one representation of public rhetoric. A new discussion within the field of public rhetoric is digital space because the growing digital realm complicates the idea of private and public, as well as previously concrete definitions of discourse. Furthermore, scholars of public rhetoric often employ the language of tourism to examine how identity is negotiated between individuals and groups and how this negotiation impacts individuals and groups on a variety of levels, ranging from the local to the global.
Public rhetoric participants A public, not to be confused with the public, is composed of members that address each other, are addressed as a group, and also subscribe to specific ideals. Michael Warner describes a public as "being self-organized, …a relationship among strangers …[where] merely paying attention can be enough to make [one] a member." Robert Asen notes that identity formation of members of a public "entails mutual recognition among members of diverse cultures." To Warner, publics are a social space where information is exchanged and is required for the exchange of information.
Counterpublics Within the public sphere, dominant publics exist whose discourse can subordinate other publics or exclude them from a related discourse. Counterpublics are the result of discourse and/or people feeling marginalized, ignored, inadequately voiced, or silenced within the public sphere. "Counterpublic refers to those publics that form through mutual recognition of exclusions in wider publics, set themselves against exclusionary wider publics, and resolve to overcome these exclusions," writes Asen. Where dominant public groups typically manufacture heteronormative public spaces and discourse, counterpublics seek to insert or reinsert voices and perspectives of and from publics. Discourse then abnormalizes or even challenges dominant public rhetoric. Warner describes the facilities of counterpublic using the LGBTQ+ community:
Within a gay or queer counterpublic, for example, no one is in the closet: the presumptive heterosexuality that constitutes the closet for individuals in ordinary speech is suspended. But this circulatory space, freed from heteronormative speech protocols, is itself marked by that very suspension: speech that addresses any participant as queer will circulate up to a point, at which it is certain to meet intense resistance. It might therefore circulate in special, protected venues, in limited publications. The individual struggle with stigma is transposed, as it were, to the conflict between modes of publicness. The expansive nature of public address will seek to keep moving that frontier for a queer public, to seek more and more places to circulate where people will recognize themselves in its address; but no one is likely to be unaware of the risk and conflict involved. As Asen furthers, "Individuals do not necessarily recognize exclusions and resolve to overcome them by virtue of their location in a social order." Asen maintains that claiming a counterpublic of this form can diminish counterpublic forms to particular contributors who share specific interests with other members but might not consider each other as allies.
Subaltern and bourgeois groups Amid publics and counterpublics, prevailing ideology, discourse, and images can create a hierarchy of group members and the rhetoric thereof. The struggle for political and social power within the public sphere between publics gives rise to dominant and weaker internal publics within a public, namely subaltern and bourgeois publics, respectively. For example, in their article "Graffiti Hurts in the United States," Terri Moreau and Derek H. Alderman describe an anti-graffiti task force, Graffiti Hurts, advocating for the eradication of urban graffiti in public spaces. This organization funded mural projects that would serve as a deterrent for would-be graffitists. While graffiti is often considered a lesser art form compared to the classical arts such as music, canvas painting, and sculpture, the mural projects "actually work to carry out a 'normative' prescription of landscape. The normalization has the ability to eradicate the potential for alternative constructions of public expression. As [Kurt] Iveson observes, 'A legal mural might have some effect in making ... people's culture more visible in public space, but often this is on someone else's' terms.'" Keith Haring argues that the dominant images of a gay counterpublic produce "clones" representing "well-built," effeminate, white males. While whiteness is idealized, racial minority imagery and representation was and remains marginalized. A bourgeois subgroup within a public is primarily composed of "private individuals…[that] do not 'rule'.... Instead, their ideas infiltrated the very principle on which the existing power is based." The bourgeois within a public represent a prevailing definition of the relevant publics and thereby control a greater degree of shared space for the related discourse between the larger public membership.
Strangers Strangers are those who are not aware of their membership within a particular public. They are capable of being members of a public; however, they can also hold no opinion or in other ways pay no attention to their potential membership to a public. Strangers are normally not those who ignore their membership (which implies one is aware of being a member of a public). To Warner, without the presence of strangers in a public sphere, public discourse cannot occur because it is a requirement for public discourse to address strangers and provide them the awareness to identify themselves as an addressed public.
