No my friend, a secular state by definition is where no intrusion of religion in the political affairs of the country is acceptable. An Islamic state, as I understand it to be, is one which, as I said, has Islam as its dominant culture, which means a certain degree of intrusion is always going to be there; legislating the ban on alcohol, prostitution, gay-marriages, gambling - all of which, in our case, is inspired by religion, is intrusive. So would be the evolution of an economic system that tries to redress some of the concerns we have about usury being prevalent and acceptable in the current system. Additionally, a Haj subsidy, facilitation of a return to scholarly tradition in Islam - the ones that produced towering intellectual juggernauts like Ghazali, Avicenna, Averroes, Mamoindes etc., would be being anything but impartial. So would having a family law, an inheritance law etc. drawn from the Quran.
However, whereas the Islamic state, collective has an Islam as its dominant culture and is thus biased towards doing what I mentioned before; it would be completely impartial on an individual level with all citizens enjoying the same rights and privileges as the other.
I would love to see a Pakistan where centres of Islamic learning are instituted by the help of the state, where an alternative Islamic economic model is evolved, where a distinct hint of Islamic unity is present in our foreign policy, where alcohol, gambling etc. are banned, where legal pluralism is instituted but where someone as honorable and upright as Justice(R) Rana Bhagwandas is made the President of Pakistan.
