But my point is that Indian Muslims are as diverse racially as their Pakistani counterparts. Yes, there are minor differences in culture and these will grow.
Over the last 50 years Pakistan has been moving closer to West and Central Asia culturally will be different. North Indian Muslim Ashraf culture that closely resembled Pakistani neutral elite culture is under attack by Hindutva cultural purists . Indian Muslims will eventually succumb but a tiny fragment as expats will survive, So you are looking at 10% of 10% of the Indian Muslim population. Even the 10% expat population is merging into the Pakistani ( mostly Punjabi) ex-pat population though the Ashraf Indian Muslims are still snooty and don't care much for the Yusufzai's and Qizlbashes. The good part is the Karachi, Bahadurabad, Sharfabad, Mukka Chowk connection with Indian Muslims is gone for good. The 1970s was the turning point when isolated from Pakistan for 8 years from 1971-1979
a new crop of Indian Muslims came up who struggled to find their niche in Indian society rather than travel to Pakistan and tear up their Indian passports on arrival. So Indian Muslims joined the civil services, armed forces, police and all the good jobs that state services offered. Only a tiny fraction made it through despite discrimination and of course 90% of these were the Ashraf.
But they hadn't foreseen the Hindutva wave These Muslims are now regretting they didn't "hop over" when India Pakistan travel resumed in 1979.
Again, we have nothing to do with them. We should leave them to their fate. So here I agree with
@PAKISTANFOREVER .
