So what?
Will they blow themselves up in shock if they learn that it is secular? If not, then it is irrelevant what they think as it has zero bearing on Pakistan's future.
China is commie yet it is our friend and our people know it. Our Sunnis also have mostly positive views about Iran despite it being a Shia theocracy. Same goes for Turkey. Being a friend of another nation doesn't mean you've to import its system.
And what has one TV show and a few twitter comments(similar comments can be seen on Pakistani actresses as well) got to do with the future of Pakistan? Nothing whatsoever... despite butt-hurt of self proclaimed Pakistani liberals who watch GOT, house of cards and movies like Titanic then talk in english language about preserving Pak culture from "Turkish aggression".
You want to build people to people relations. Not kill them. We can't relate with Chinese at all, and most people don't want to.
Relations with Turkey are less grounded in strategic relations and more in religion and history.
