Here in Pakistan, as the situation is v complex, the most apropperiate way to protest is in peaceful manner by keeping oneself perfect in accord to Quran then join an organization which is, sincerely, working for the positive change in the system like Tanzeem Islami founded by Dr. Israr Ahmed (Late) and headed by Akif Saeed (tanzeem.org). They are teaching Quran first then they 'll protest in an organized manner, when there 'll be a large number of True Pakistani Muslims in near future. They 'll consider each and every policy contradictory to Quran and 'll try hard to correct it whether it would cost lives and blood.
If you, as a being, want to maximize the value your efforts to bring a positive change in Pakistan then, first you should change yourself in accord to Quran (your own words, Maroof) then by joining tanzeem.
It is the most comprehensive and effective way to protest.

I have mentioned the dense and complex situation i.e as we have to force our Muslim brothers in government, not Non Muslims, so we 'll have to avoid killing or harrassing them untill they do not exceed the limits. Moreover, in the case of armed or militant resistance they may use the Pak Army or other Law enforcement forces against us, which is not our desire as we need peace via peace.
Hope it is complete and desired answer, if you agree then don't wait for miracles and do join.
