Not having read Gore's book, though I doubt Kelly has either, I can't be certain. But, it sounds as if the Gores are discussing how the concept of family has changed, not advancing any particular agenda about what the family should be. Unlike Kelly, who thinks homos shouldn't have kids. Because, you know, we wouldn't want the species to be unhappy.
