Among the many commendable things the state of Pakistan achieved is the objective resolution and declaring declaring qadiyanis to be what they actually are - non-muslim and serious anti-islamic cult. Yes , yes , yes Islam definitely mandates regulation of public space by the state in favor of Islam and Islamic principles because it is the only truth and guidance for mankind ordained by the Creator of everything that exists. Its the duty of the state that Muslims are NOT subjected to corruption by deviant, heretics and falsehood of non-muslims and that entails there is restriction on what one can say in public if that involves calling people to false, trying to deceive people and lead them astray.
The very notion that state has nothing to do with ones religion is alien to islam and is NOT from the rich islamic history & tradition but it is imported from anti-religion post-"enlightenment" europe. There is absolutely NO room for such non-sense in Islam. Why should it be that muslims who are in majority organize their state polity based on alien ideas and beliefs of fringe minority - liberals, secularists & qadiyanis? By any measure of commonsense & logic that is absoultely absurd.
Also, one has to note that qadiyani cult originated in India and unfortunately this cult group thanks to british patronage have considerable numbers in the subcontinent specially India & PAK. Thus it was imperative on PAK state to make sure that the deception & corruption of this cult group was called out & prevented by the state. PAK owed it to the Muslim world and they have done their job. Congrats to my PAK brothers for that.
