Punjabi students Can they study in universities of Karachi safely

Perhaps the title of my thread is not correct. I do not say that I will be ( allah na karay ) a victim of Target killing in Karachi by some element like JSQM or MQM. I will be inshahallah safe and sound at NUST Campus and will also get hostel at the end of 1st semester but…
I was told in reality by my friends and relatives that Punjabis are irrationally hated in Karachi. The people over there have prejudiced opinion for us. They will not trust me etc etc.
By-the-way, this is not my opinion, I just wanted clearification from actual karachi people. When I was planning to go to karachi, I was very happy. I consider Karachi a fantastic city. Where lies the manufacturing industry, the economy, the fashion industry and all the Television media.
The classes will commence from 5th September and I will inshahallah join PNEC.
