As I mentioned "West of the Indus". Which is why many Indian Muslims were opposed to the Idea of a separate country in that particular area of then united India. Anything beyond Lahore was/is still considered the wild west and people were considered fools if they wanted to go there just for the sake of travelling.
However, to say that extremism is confined to the west is unfair, we must not confuse cultural conservative ideals with extremism. The first winds of extremism originated from Deoband which is nowhere near the west. It was these very deobandis that opposed education, then they opposed integration , then they opposed the Muslim league.. and as
@Imran Khan puts it very well; will say/do anything to ensure the survival of their sect.
As mentioned earlier the true winds of change in Pakistan began with Ayub Khan and his fake history books and the Saudi "Invasion" that came in lieu of the Afghan war in Pakistan. India too has been getting the GCC extreme winds and they will eventually hit through(or already have slowly) thanks to the internet. But unlike Pakistan these are not organized politically or as an institution but in cells within the younger population.
