I respectfully disagree. Different societies have evolved with different levels of religion over time and like you have said plenty of times before, muslims are not a monolith. How an Albanian muslim thinks will be vastly different to how an Afghan muslim thinks because they have different perspectives - Albania owing to its location in south eastern Europe and its close proximity to European countries would be far more liberal in its views than say Afghanistan. Majority of central asian states are liberal in their views on religion because they were part of the Soviet Union and therefore would've had greater exposure to communist ideologies, which generally views religion as an impediment to progress and development. The Turks are generally on the liberal side because Ataturk was a staunch secularist and nationalist who didn't mind abolishing the decrepit Ottoman empire and therefore most of the present day Turks' views are influenced by his policies.
In contrast, Afghanistan has been in turmoil almost ever since India and Pakistan became independent countries. It has been under foreign occupation and also has been the lab for a variety of islamist organisations to experiment. It has never got the chance to progress or develop as a nation, and do the process of nation building like other countries. So an Afghan's views would be vastly different to what a Bosnian or even a Kazakh's views would be. Pakistan, on the other hand, was probably envisioned by Jinnah to be along the lines of the present day Turkey, but it soon got into the hands of islamist leaders like Zia who reimagined the constitution of Pakistan on islamic lines.
I'm not against religion, but it's my firm belief that any nation which is styled on religion will not succeed. It may continue to "exist", but it won't succeed. There's a difference between existence and success. I'm staunchly opposed to hindu nationalism in India for the exact same reason. Now it might be far easier for me to express my opposition against the imposition of religion in public sphere but for muslims, it might be difficult because any such opposition by muslims against undue influence of religion in society would be viewed as apostasy and therefore will never get popular support as muslims are generally among the most religious. And so it would not be a surprise to see Pakistanis having very conservative views on religion because the nation, whether or not it was imagined on islam by Jinnah, has come to exist on islamic lines due to what happened after his death.
While it's possible that Pakistanis support harsh corporal punishments on shariah due to extreme frustration with corruption and theft by politicians, it cannot explain the overwhelming support for death penalty for apostasy or heavy opposition against family planning, or favouring harsh punishments for adultery, blasphemy, etc. I just think Pakistanis are generally very conservative when it comes to religion and so are more prone to supporting laws or having views on punishments as it was revealed in the shariah. That is not because they're inherently violent or aggressive, that is because they are arguably among the most religious even in the muslim world and probably believe following liberal versions of laws as straying from their religion.
