I agree. However, here is the problem. If members of the Taliban hurt a male relative of a woman for not wearing purdah, have they not broken the law and committed assault?
If they have broken the law, they should be arrested and put on trial.
However, when security forces try to arrest taliban members for breaking the law, they get attacked.
As police don’t have the same kind of firepower to fight back, they have to bring in the army.
When the army gets involved, more Taliban come to fight. Which leads to gunning down on all sides.
The alternative is to excuse Taliban members from prosecution for breaking laws; which sets a bad precedent for every armed group in Pakistan to try the same (witness the MQM’s reign of terror over Karachi, which only ended when enough of them were gunned down).
You’re probably right when you say that Pakistanis are not first-rate Muslims. However, forcing them by brute intimidation to follow Islam is only going to drive them to turn against Islam. The Islamic state in Medina was not forced upon its people; they were willing to live by and follow Islam completely first, then they made the Islamic state. Simialrly, in Pakistan the challenge is not how to force people to obey Islam. The challenge is how to make them want to follow Islam.
Intimidation is not a substitute for dawah.
