This study examined the Yoruba nation secessionist agitation from the viewpoint of stance and ideology in its discursive engagement on three popular Nigerian virtual communities: Nairaland, Gistmania, and Naijaloaded. Data were subjected to the theoretical and analytical paradigms of appraisal framework and critical discourse analysis. Two voices were identified in the study: the anti-Yoruba nation and the pro-Yoruba nation voices. The anti-Yoruba nation voice projected three ideologies: reformist, conservativist, and pessimist, while the pro-Yoruba nation voice projected separatist and arbitrationist ideologies. These ideological constructs were indexed by overlapping instances of appraisal subsystems and discursive strategies of perspectivisation, nomination, negative evaluative attribution, depersonalising metaphors, intensification, and intertextuality. Most participants suppressed antithetical stances to project an authorial ideological stance on the secessionist movement. Given the divisive nature of the secessionist stance, inflammatory and aggressive expressions as dominant discursive patterns are inimical to the efforts to promote inter-ethnic harmony, patriotism, and national integration.
