Re: Ancestors of Pakistanis were NOT Hindu!
Irony is that Islam, one pillar of Pakistani identity, is Middle Eastern but Urdu (or Hindi) is Hindustani. Geographical proximity, combined with racial and linguistic affinities, may gravitate the things in favor of Hindustani Civization. As for Islam, it would have little impact for Hindustan already is a great admixture and melting pot of religions and races. It has 130 millions Muslims and Islamic institutions like Deoband, Nadwatul Ulama etc.
Otherwise also, religion, and that too a universal religion like Islam, cannot give a people an identity.
