Hindus in Pakistan want to leave for many reasons:
The BJP govt should make patriation of Hindus in Pakistan and Bangladesh back to India a higher priority. There's no reason not to do this -- there are no negatives and only positives. Ultimately, it could even help tilt the balance of future Indian elections in BJP's favour. Ram temples and cow protection won't change ground realities as much as repatriating Hindus to India would.
