Why the term "fairytales?" The distinction is between a belief-based perspective and an empirical perspective. The former includes all ideology, to include Liberalism, as well as theology.

Ideology was invented to replace theology for governing the governance of society, but its inadequacies are being exposed. That is the situation we are now in: the failure of ideology has caused people to turn back towards other belief-based forms of dealing with the problem of governance--to include purely personally informed fantasies that aren't even related to any ideology or theology: just ad hoc puffs of thought informed by nothing but a person's emotional state.

People who are empirically inclined might find interesting an empirical approach to an ethic to govern governance, one that contains no belief. It would take us "Beyond Liberalism" (which is the only ideology specifically concerned with understanding what justice must be). [The linked article is here in Medium, but not behind the paywall.]
