Despite being an admirer of PTI, I would say that PTI together with MQM-P has not been able to liberate Karachi from mistreatment by PPP and Sindhi nationalists. All due to 18th amendment provincial government can do whatever it feels like. Wrong census was done when Nawaz Sharif was in PM office, and its an open secret how he and Asif Ali Zardari would keep on scratching each other's back for 10 years.
Muhajir community was stabbed in the back by it's own people, and in 2010 the trio of Altaf Hussain, Haider Abbas Rizvi and Faroque Sattar had sealed their fate through 18th amendment . Neither of the three are ready to apologize to Muhajir community, plus there are still many people who think Altaf Hussain is "Father" of Muhajir nation. In reality Altaf was in bed with Sindhi nationalists and made Muhajirs fight Punjabis and Pashtuns, Army and everyone else. Now he's acting like a cheerleader of Sindhudesh.....even though if (God forbid) Sindhudesh does appear on world map then guess what would be fate of all Muhajirs, Punjabis, Pashtuns, Hazaras, Hindkos and everyone who's considered an outsider in Sindh
