They want Lal Mosque type sanctuaries all over Pakistan. And PML (N) and their chamchas are sympathizing with them.

I didn't expect that from Mr Altaf Hussain and MQM that they despite being Anti Extremism would support a person i.e. Musharraf who used Sipah-e-Sahaba and other such rampantly deviant Sectarian Organizations to crush the Shia Community of the Northern Areas of Pakistan? Really [Altaf Hussain aur MQM ki Aqal waqai Chaupat ho gai hai].
What about another filthy expose about the then Brigadier Parvez Musharraf under Jamat-e-Islami and Mullah Mawdoodi's Reincarnation of Satan i.e. General Ziaul Haq. With proper references and notes:
1 - During Zia-ul Haq’s rule, General Pervez Musharraf, then a Brigadier, was assigned the task of suppressing the Shia revolt against the Sunni-dominated administration in the Gilgit region. Musharraf used Pathan tribesmen from NWFP and Afghanistan along with his troops to silence the Shias. In the wake of this operation, hundreds of Shias were butchered and displaced from Gilgit. The operations were widely reported in the Herald, a monthly magazine of the daily Dawn in its April and May 1990 issues. It is also said that the Wahabi Pakhtuns who raided Gilgit under Musharraf’s command were led by none other than Osama bin Laden.
1 - According to a Herald report of May 1990, “In May 1988, low-intensity political rivalry and sectarian tension ignited into full-scale carnage as thousands of armed tribesmen from outside Gilgit district invaded Gilgit along the Karakoram Highway. Nobody stopped them. They destroyed crops and houses, lynched and burnt people to death in the villages around Gilgit town. The number of dead and injured was put in the hundreds. But numbers alone tell nothing of the savagery of the invading hordes and the chilling impact it has left on these peaceful valleys. 
2 - Another point against General Musharraf being a liberal is that most of his political support over the last eight years has come from pro-Islamist conservatives. For those that might have forgotten, the one vote that allowed the pro-Musharraf coalition to win a majority in the National Assembly came from the late Maulana Azam Tariq, leader of the sectarian Sipah-e-Sahaba. 
3 - Musharraf has plainly given the religious groups more free rein in the campaign than he has allowed the two big parties that were his main rivals. In Jhang city, in Punjab province, Maulana Azam Tariq, leader of an outlawed extremist group called Sipah-e-Sahaba, which has been linked to numerous sectarian killings, is being allowed to run as an independent—despite election laws that disqualify any candidate who has criminal charges pending, or even those who did not earn a college degree. 
4 - And while the Sipah-e-Sahaba Pakistan and the Lashkar-e-Jhangvi stand officially disbanded, their most militant son and leader, Maulana Azam Tariq, an accused in several cases of sectarian killing, contested elections from jail - albeit as an independent candidate - won his seat, and was released on bail shortly thereafter. The fine line between an outright violation of the law and its insidious subversion by those who appoint themselves its custodians has been blurred so often in Pakistan's chequered political history, that is has now become par for the course. The irony is when the architects of that subversion or violation are those who frame the laws themselves.
