Hmmm....
In case you may have forgotten:
*Honor killings are carried out by religious Muslims, not uneducated or poor.
* Honor killings carried out by Muslims are carried out for religious reasons - a family member is accused of committing apostasy or having premarital relationships of some sort - all strictly forbidden under Islam.
*Actual honor killings in Hinduism are rare and Sikhs (a religion that is a hybrid of Islam and Hinduism) honor killings seem to be limited to wives, unlike Muslim honor killings where children are just as vulnerable
* Honor killings are universal in the Muslim world - all Muslim peoples, regardless of culture, geography and so on are known to commit honor killings.
* Islamic Law in several Islamic nations condones or has condoned honor killings. The Iranian Mullahs would be happy to testify that they condone honor killing violence. It isn't secular statesmen in Iran who make and enforce the law in the Islamic Republic.
* The law of retaliation in Islam provides convenient loopholes for honor killers. Honor killers in Pakistan are usually set free after the family of the victim (the same family as the murderer) requests a pardon. If Muslim society is generally supportive of honor crimes under an Islamic legal system, then it is virtually impossible for the courts to punish the perpetrators.
* Muslims, a religious minority in the world, carry out a majority of honor killings.
