IS It A "MuslimThing?"

I did an item recently about a Muslim man murdering his two daughters because they were seeing non-Muslim boys. In another case, a Muslim man killed his daughter because she refused to wear a Muslim headdress. Soon, I got a reply from a woman who wrote a book on a similar subject, insisting "honor killings" were not about religion, that they predated the Muslim religion. That may well be true, and "honor killings" may not belong exclusively to Muslims. But every instance of it I've seen recently involves a Muslim. The fact is, even if it isn't in the Koran (however they spell it today) it is something that has been fully embraced by the Muslim extremists as their own. (Human Events)
