There is a difference between being educated and being enlightened.
I’ve noticed that liberal Muslims subscribe to a “liberal interpretation” of the scriptures but do not dispute its centrality like Western secularists do vis a vis the Bible . While there are many liberals there are very few who believe that scriptures should not form the basis for morality. Its rare to hear a relative approach to the religion; its sanctity and divinity is absolute both among liberals and conservatives, they differ only on interpretation. Theists, of all stripes and denominations, must eventually understand that the only way forward for coexistence is to be fluid and flexible vis a vis theology. For it to survive religion must adapt to suit the need of our time otherwise it’ll be consigned to fecund, poor enclaves in a rich secular & aging world.
Also the assassin of the Governor belong to the Barelvi sect, which is the more “liberal” and “Sufiesque” Sunni sect of Pakistan. In fact the Barelvis are condemned and attacked by the more militant right-wingers for their esoteric interpretations and for their traditionalist approach (as opposed to the reformism and puritanism of the Salafist/Wahabis).
