lolzzzz you are such a joker. If your so called MQM was so popular in karachi, why doesnt your leader come back? You must follow MQM. Lets put it in easy english for you. MQM is the reason why karachi has become a war zone. MQM has killed and kidnapped thousands of people. They are known for "Bori Band lashain". They have their own torture cells all around the city.
In easy urdu : MQM Wajib ul Qatal hai. In ko khatam karo or sowaab kamao. In logon nay bohot logon ka haq mara hai, bohot logon kay ghar ujaray hain, bohot logon ko taqleef di hai. Is gandagi ko khatam karo karachi main se.
MQM did have full support before, even now it's still high, officially me and no one in my family friends actually vote for MQM, we know they're just like any other party now. But unofficially we acknoledge that MQM is the lifeline of peaceaabiding karachiites.
So no, MQM being the least of the three evil is third in line for 'wajib ul qatal' as you say. Fck up the order and you no longer have karachi existing
