While there is no national consensus in Pakistan about their identity - whether that being scions of IVC or any other civilization, there is a consensus in India - that we are scions of multiple civilizations.
While Pakistani's agonize whether they are Islamic and their culture is Islamic derived and have nothing to do with IVC which was the genesis of Hinduism , we on the other hand claim all religions residing here as Indian.
The dichotomy of Pakistani thinking is the fact that while a minority section like yours would like to claim IVC and all that belongs to the geographical land called Pakistan, there is a majority section which has worked really hard to ensure Pakistan has no links and no claims to anything that is not Islamic.
And the physical manifestations of this thinking is how Pakistani people are radicalized in Islam into making life of people of other faiths in Pakistan hell. The stone is set, the dye is cast. Majority of Pakistan would like to be associated with Islam and Islamic culture and history which is predominantly from West Asia.
Had you been like the Iranians, who even after becoming Islamic are proud of their pre-Islamic ancestry and past and embrace it, then it would have been a different issue altogether.
But your leaders and masses have not chosen that route.
You are a very small minority in Pakistan who wants to change that - but your country and people have long forsaken that. For had you chosen the other path, you would have been an inclusive society in terms of religion. You are not.
The contrast on the other hand in India as aptly put by Joe is:
"The answer is that I need not. We inherited it, proudly,
including all, excluding none, and we continue to build.
No quest for identity for us, for we know, and move ahead secure"
