> genocidal violence against Muslim Indians.
What's this about? Partition killed as many Hindus and Sikhs as Muslims and pre-Independence India had little communal violence that wasn't explicitly fomented by the British in order to serve their own ends.
If you're so well read in south asian history, you should also know that there are more muslims in India than in Pakistan and that pretty much none of them would like to switch places with their Pakistani siblings.
