you guys were initially claiming it was just Punjab
what you mean by "you guys"? I don't work for mqm, or have a membership, or ever lived in Karachi, Hyderabad or any part of sindh. So there is no need no personalize it. Having different political opinions does not mean, that you should take your unpatriotic-tagging machine out.
About MQM, being an ethnic party, I believe the fact that they changed its name to Mutahidda, from Muhajir, shows a desire to break out of ethnic shell. Just because most muhajirs vote for it, should not make it a ethnic party anymore. Remember most punjabi's vote for PML-N.
Also don't cry when word "Nawaz Shareef" is used. If you read it carefully, I said I don't believe he is racist either.
