Are you talking about the same Karachi that I am from? I have seen street guys threatening my chacha for a damn “khaal”. I have heard from family members that they also forced people to give money for “bhai’s” walima in London. Are you naive or just ignorant?
I even heard a personal account from an “ex-member” how he had to leave the city for a bit after he left the party because he new what will happen if he stays there. This usually happens in gangs and not in political parties.
And just as someone else said, where there is smoke there is a fire. People are not stupid. They show up for jalsas, they vote for MQM because they KNOW if they don’t then what will happen to them.
