Re: Secular Pakistan
Muslims in India increased because of Sufi preachers - Mian Mir, Bhittai, Gunj Baksh etc - not the deoband type turban toting - shalwar above takhna types.
The 700 million Hindus are still there because the Mughals - almost all of them were not really strict Muslims (Aurangzeb was a notable exception - who went on a Temple/Stupa destroying mission).
Ever heard of Akbar and Din e Illahi? He’s a Mughal - would you call him a Muslim?
