Just to make it clear. Pakistan law is heavily Islamic law. At the start we had British law but as we went forward, Islamic law has taken great roots and right now has greater Islamic identity than British law. The qanoon e shahadat law is based upon Islamic law, hudood laws, divorce laws, has mehr laws and in fact pakistan jurisprudence has Islamic law for all sects which means that a shia can get tried and demand justice in accordance with shia law. The court hierarchy is indeed western but the law practiced is Islamic in its nature.
Infact we are an Islamic country that have defined Muslim definition as well as constitutionally the parliament cannot pass any law that contradicts Islamic law system.
I think we have done wonderfully creating a mix where majority is Islamic whilst the shade of British is still retained.
As for minorities. Islam provides complete protection to minorities and allows them to practice their religion freely without any hindrances. That is islam and if we have the largest cross or churches, temples or gurdwaras then it's our pride that we have protected our minorities as per islam and we are NOT ttp, Taliban or Isis unlike a certain country at our west. Our minorities are to be protected and will be protected.
As for brewery. In CRPC there is complete penal code law about drinking for Muslims which is a punishable crime. Only non Muslims are allowed to drink and that too not in public. At one time we used to export the murree beer and earned billions but that is off and unlikely to restart again.
This is a pretty Muslim country.
