It argues that this understanding of deliberative democracy fails to adequately consider the asymmetries of power through which deliberation and consensus are achieved, the inter-subjective basis of meaning, the centrality of respect for difference in democracy, and the democratic role of `like-minded' deliberative groups. The deliberative public sphere must be rethought to account more fully for these four aspects. The article draws on post-Marxist discourse theory and reconceptualizes the public sphere as a space constituted through discursive contestation.Taking this radicalized norm, it considers what research is needed to understand the democratic implications of the formation of 'like-minded' groups online.
