They do. Just that the they don't fall for your ridicalous claim that they were Hindu's. A term only coined few centuries ago and even then to a concept so vague that it can be applied to anything.
Can never be restricted within 'patch of dirt' as
@Taimur Khurram would say. As a identity or concept 'Muslim' will never be restricted to a geography. It goes against the very notion of Islam that is universal.
And the very heart of the Pakistani crisis of identity is trying to brand a religion - Islam that is
global and universal. This will never work. How the hell can people even think they can tie down a uinversal faith that has global presence and majority religion in nearly 40 countries be branded into one geography on the Indus Valley?
Ridicalous ....
Ps. I looked into this in another thread. The contradiction is laid bare in the map below.
