Thats going to be hard because Pakistan was created as a homeland for Muslims? If there were no Muslims in what was India then there would have been no reason to create Pakistan.
So religion should be a distant second? Should those pakistanis that pray Namaz, stop? Should those Pakistanis who fast during Ramadan and go to Hajj stop? Should those Pakistanis who respect the elderly, love the younger ones, give alms, wish for their neighbours what they want for themselves, stop doing all this?
