Ok, so this might be a bit of a controversial topic. The mods can close this one down if it gets out of hand. I'm just opening this one for intellectual purposes and so that Pakistanis can think about the possibilities.
The main reason for me to talk about this is that I have observed many Pakistanis talking about Muslim rule. Post Independence, there was the Kashmir dispute that is still going on to this day. Do Pakistanis think that if the whole of India would have been converted to Islam like them by the Turks, Afghans, Uzbeks, etc, that there wouldn't have been any Kashmir headache for them? Do you guys feel that the invaders should have been more serious about Islam and the conversion of kaffirs of the Indian subcontinent to that religion?
Would India and Pakistan still would have been separate? How would the Muslims looked at Hinduism which would have been an extinct religion by now? Would Muslims have an affinity for Hinduism like the Greeks have for the Greek philosophers and the Persians have for the pre-Islamic Persian empires?
Would Indian origin Muslims would have even risen up against foreign Muslim rule? Or would there have been just a continuation of Mughal rule? Would the Turks might have migrated in more numbers to India to consolidate their rule or spread the extent of the Ottoman empire?
Would the Indian Muslims had allowed that?
