i think you are wrong here (or if express news presented this then they are wrong). Mostly madrasses in pakistan belong to sunnis or new immargining branch called as tableeghi jamat(i think they are also same as sunni, just emphizing is different). Both have no conflict in practicing. Both uses same types of books. Just with the difference is that sunni madrass emphasize more on practice and worldy affairs and somewhat sitting with alim (scholars), while tableeghi jamat more emphasize on inviting other and practicing correct sunnahs. while you are pointing on salafs, then for your information tableeghi jamat is more close to sunni, and follow hanfi school of thought. while salafs follow predecessors of four imams of sunnis, or predecessors of imams of shias. so don't come under these lines. I presonnaly visited many madrassas, but never see any existences of salafs. You can say Afghan talibans were combination of both salafs and sunni, but they more closer to sunnis of south asia, since, they studied in these madras. Hanafi school of thought is majority among other groups of south asia, so can't be 20% atleast. Also, i don't know how express news actually indicated that they 90% of belong to salafs? did they tell them that they are salafs? or they try to practice in front of express news survey team. A propaganda started from west, & even wahabism (name) to arabs is also given by the west (check the history record). While we all know abdul wahab never had much supporters, neither the saud's wife (not saud himself) who followed abdul wahab had any child who ruled in future.
This is very important for all members, since i saw this propaganda machine is growing rapidly.
