More broadly across time and cultures, it seems, one perennial piece of advice to father has been the importance of acting tenderly toward their children. The New Father, it turns out, is an old story.

Even with all its problems, I will support marriage as an institution until something better comes along.

When a man does not live with his children and does not get along with the mother of his children, his fatherhood becomes essentially untenable, regardless of how he feels, how hard he tries, or whether he is a good guy. Almost by definition, he has become de-fathered.

Today an American child can reasonably expect not to. Fatherlessness is now approaching a rough parity with fatherhood as a defining feature of American childhood.

Children have a primal need to know who they are, to love and be loved by the two people whose physical union brought them here. To lose that connection, that sense of identity, is to experience a wound that no child-support check or fancy school can ever heal.

We would be more American on the day we permitted same-sex marriage than we were on the day before.
