> "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.

This article can be interpreted as evidence that radical democracy actually works and the root of democracy ought to be a diversity of minorities all advocating for things we could call their essential beliefs, and a healthy, free society is one in which on any given issue the majority is flexible enough to accommodate minorities that have stronger preferences.
That is, a prosperous, cohesive society isn't one that tends to homogeneity but is instead driven by its heterogeneity. Furthermore, a prosperous, cohesive society isn't based on rigid principles, but flexibility and the ability to evolve its structures to accommodate more and more diverse groups.
Seems legit to me. Most homogeneous groups in history seem to either arise from a founder effect or maintain their homogeneity through dehumanizing tribalism and Incredible Violence.
