Several Oklahoma lawmakers plan to return copies of the Koran to a state panel on diversity after a lawmaker claimed the Muslim holy book condones the killing of innocent people. The books were given to Oklahoma’s 149 senators and representatives by the panel, the Governor’s Ethnic American Advisory Council. At least 24 legislators, including Representative Rex Duncan, a Republican, have notified the panel they will return the gift. Marjaneh Seirafi-Pour, chairwoman of the council and a Muslim, denounced Mr. Duncan’s assessment of Islam. I know he referred to Islam as an ideology, Ms. Seirafi-Pour said. That is not a fact. It is a religion. It is very peaceful, very inclusive.
