He writes at Quadrant:

The link between Obergefell and the Planned Parenthood controversy is the family—in particular, the death of the traditional Western conception of family. Marriages no longer necessarily produce children. Children are no longer necessary products of sex, but only an optional by-product. The old idea of family is dead in the West. These two events are evidence of its termination. In order to make a plausible defence of the traditional conceptions of sanctity of life and marriage, the centrality of the family must be recaptured.
