MQM suspends/terminates membership of anyone who is found to be violating party discipline depending on their particular cases. For ex. if your area unit incharge is harassing you then he will be kicked out of the party and so on. They try their best to weed out the bad seeds and their process and their discipline is better than any other political party. I'm sure that criminals are also reported to concerned agencies.
Oh really? that is news to me. Perhaps you can explain why Ajmal Pahari, Ishrat Ibad, and many others (including Altaf himself) are still very much part of MQM?
Secondly, why do MQM members have to take an oath such as below?
“I,…believing that Allah is here and watching over me, swearing by His book and my mother, take oath that I shall remain loyal to the MQM and Altaf Hussain for my whole life. I will not take part in any conspiracy, planning or action against MQM or Altaf Hussain and I will not maintain any link with anyone who is involved in any of the acts mentioned above. I swear by my mother that if any conspiracy against MQM or Altaf Hussain or any act harmful to them comes into my knowledge, I shall immediately inform Altaf Hussain or other main leaders, even if the conspirators be my brother, sister, mother, father, any relative or friend…I swear that I shall keep every secret of my party and regard it more precious than my life. I swear that I shall accept Altaf Hussain’s decision as final in any matter and obey all his decisions. If I disobey any of his decisions, I must be regarded as a traitor. I swear that I have and I will have blind trust in party leader Altaf Hussain…May God help me to remain firm and loyal to the MQM.” [From the book: A People of Migrants: Ethnicity, State and Religion in Karachi by Oskar Verkaaik , page 72].
Am looking forward to your factual arguments..
