2. Agreed that there was mass migration both ways. But consider these things. Islam is the fastest growing religion in India and Muslims make up ~15% of Indian population today, whereas in Pakistan minority population has fallen from ~15% to less than ~2% since independence.
3. Predicted correctly? How do you prove that Indian Muslims are living worse than Pakistanis? A couple of communal riots in India don't prove anything, considering how big India is. Whereas, the daily bombings, drone attacks, ethnic riots in Pakistan don't give encouraging picture about Pakistani Muslims, the very bunch for whom the country was created.
And as I said in another comment below: "Except politically and militarily, Indian Muslims have outperformed Pakistani/Bangladeshi Muslims in all fields. Just take as fundamental as literacy rate. Indian Muslims have better literacy rate (59%) than Pakistani Muslims (50-55%)." To add to that, the richest Muslim in the world is Ajim Premji, an Indian software mogul, not some oil sheikh.
