" Like the market, conjugal society, consisting of marriage and family, is not the creation of the state. It is a pre-political institution, rooted in sex difference and procreation. Given the pre-political nature of conjugal society, the state regulates it rightly by recognizing it as a natural fact with its own norms and purposes. The state ought not treat conjugal society as its own creation. Where there is evidence that parents are failing in their duties to each other or to their children, the state may intervene. Absent this, however, the state ought to leave conjugal society, rooted in the union of one man and one woman, alone. "
