Forget it. Pakistan can never be secular now. The political class, the judiciary, the army, the police, the education system. Everything is in control of people like Hafiz Sayeed. It is a self propagating system of extremism.
Extremist grow by linking their activities as part of Islam. So no Muslim can oppose it and the ranks of extremists grow day by day until they have turned everyone in their country to their kind. The remaining secular's, Moderates, progressive would be extinct with time.
I for one would be shocked if Pakistan is really able to control growth of extremism. It's a tall order and I am not sure if Pakistan's society is capable to do it. I wish they do it, but I don't think they will be able to do it.
Unless extremism is controlled, I would be surprised if Pakistan does not become another Syria/Libia/Iraq in future or disintegrates before 2030. Growing extremism only takes a country in one direction - self destruction. If anyone has doubt, tell me one PROSPERING extremely radicalized country in world?
I wish extremism is controlled, and I have a moderate progressive and scientifically advanced Pakistan in my neighborhood. But my wishing cannot change the mind of the extremists already in near total control of Pakistan society.
