Prostitution, racism, classism and superstition is rampant throughout the society. These are just a few of the things found in the so called Islamic republic.
It's quite evident that the nation is far from Islamic, and ofc, I do think that needs to change. However, that doesn't suddenly change the current nature of it. So, for Pakistanis to like Pakistan because it's "Islamic" is highly fallacious. It's also rather odd that just one nation could somehow claim to carry the burden of Islam out of literally dozens, or that it would base its national identity off of a religion. Your religion and your culture are two different things. A Muslim Pakistani and a Muslim Arab are the same religion, but don't come from the same cultural background.
