Pakistan could easily aborb those people if the government also brought in a population control policy, it is going to almost double its population in the next 60 or so years anyway.
I really fail to understand why Pakistani are so concerned with what happens to Indian Muslims, it seems we like to pick and choose which Muslim group we feel sorry for, in order to mask our desire to undermine a country. I certainly do not see a lot of posts sympathising with the Uighars who are actually being culturally genocides on an industrial scale, instead we shed tears over a handful of Indian Muslims being killed in the usual Indian communal violence.
This backlash against Muslims around the world will continue due to our group's low IQ behaviour, India was under the rule of the secular Congress for decades and yet Pakistan kept agitating because it is simply a Muslim trait to desire the destruction of others rather than building ones self up. I certainly wouldn't expect Muslims in Pakistan to not vote in a radical Islamist party if 15% of our population was Hindu and kept demanding special rights and asking for the breakup of our country.
