Jacoby and NOM fail basic logic. They can't explain why marriage should be denied to same-sex couples raising children, but is allowed for elderly (infertile) couples to encourage domestic stability and love. Want to know why? Marriage historically was an economic transaction, where a woman was sold from her father or brother, to the father of the groom, who allowed his son to marry the woman. In more modern times, it has required the implicit consent of the couple, but the structure of the ceremony in most cases ("Who giveth this woman?") is still handing over the woman as property to her husband. None of your arguments make any sense in a legal system that values individuals.
