Dr. Jennifer Roback Morse, founder and president of the Ruth Institute, a project of the National Organization for Marriage (NOM), argues that gay marriage creates “structural inequality” for children.

During an appearance Tuesday on Lutheran Public Radio's Issues, etc., Morse said that the “essential public purpose” of marriage “is to attach mothers and fathers to their children and to one another.”

“And, obviously, same-sex couples are different, with respect to that purpose,” she said.

“Even though some married couples don't have children, the fact is every child has parents and every child deserves to know who their parents are and who they are. What their genetic background is. What their social-cultural-emotional background is. Every child is entitled to that.”

“So in order to make the same-sex couples equal on their wedding day to the opposite-sex couples, you're telling children that some of them are going to be more equal than others. And I don't think as a society we really have the right to just be doing that. To have the state intervening and creating that kind of structural inequality among different children.”
