Absolutely Not.
Am not a JI voter as such but the Pakistanis need to recognise this vicious and divisive propaganda to damage Pakistan further from within.
Some folks have the tendency to think/act emotionally and impulsively, not with maturity and tolerance. Pity, that any time people hear something that is against their views or policies, they would have a knee-jerk reaction one of the fundamental reasons behind our long history of "structural violence" by the state against its own people. from East Pakistan to Balochistan to Karachi to FATA, that has resulted in a highly dysfunctional state that we today find ourselves in.
Banning Baloch/Sindhi/Pashtun/Mohajir/religious parties (or even media groups), or killing political leaders or investigative journalists, will never be the solutions. Your system should be mature enough to acknowledge/respect dissent, give people their basic rights and negotiate mutual differences amicably. Democracy means self-government and what self-government are we talking when both people and institutions can't govern themselves, when there can't be a rules-based system (not based on personal/institutional likes/dislikes).
Its high time to start thinking of collective good of Pakistan, not individual sacred cows, and for that its imperative to: (a.) reflect on the message instead of shooting the messenger, and (b) address the causes of the issues/malaise afflicting the Pakistani body-politic instead of proposing symptomatic treatments to the issues that surface.
