As part of an ongoing legal and social struggle in Pakistan related to how women are treated, the country recently revised its rape laws, moving handling of rape cases out of the jurisdiction of Sharia (Islamic law) and into the civil courts. The six-party Islamic alliance MMA is protesting this move.
Why is this significant?
The civil code in Pakistan is influenced by British law, which means that a rape case would be prosecuted much in the manner that a westerner would expect (that is to say, not always effectively, and often allowing damaging attacks on the victim's reputation, but with the basic rules of a criminal court in place).
Under Sharia, the victim of a rape would need to have four male witnesses to the crime, or else she would be punished for adultery.
The MMM is protesting that this legal change will encourage "free sex" as well as "lewdness" and "indecency."
It is hard to express more clearly than in this example how certain aspects of fundamentalist Islam -- as it is practiced -- are incompatible with a sane, civil society. As Wafa Sultan said, the current problem is not a clash of cultures, but a clash of eras. Right now, it is medieval Islam versus the modern world. And much as medieval Christianity gave us such horrors as "Kill them all! God will know his own.", medieval Islam gives us horrors like assuming a woman is adulterous because she wasn't raped in front of enough witnesses.
