According to Laclau and Mouffe "Radical democracy" means "the root of democracy". Laclau and Mouffe claim that liberal democracy and deliberative democracy, in their attempts to build consensus, oppress differing opinions, races, classes, genders, and worldviews. In the world, in a country, and in a social movement there are many (a plurality of) differences which resist consensus. Radical democracy is not only accepting of difference, dissent and antagonisms, but is dependent on it. Laclau and Mouffe argue based on the assumption that there are oppressive power relations that exist in society and that those oppressive relations should be made visible, re-negotiated and altered. By building democracy around difference and dissent, oppressive power relations existing in societies are able to come to the forefront so that they can be challenged.
