Diversity Where It Matters

People who claim that it is diversity that makes American society great may have a point, but probably not in the way they think. Many who talk about diversity, as in the hyphenated culture (rather than the melting pot, see Adnan Barqawi here), are liberals who espouse same-sex marriage. But let's take them at their  assertion: If it's diversity of culture that makes society great, that gives our culture such richness, and provides for instinctively different perspectives, shouldn't the most basic, elemental, microcosmic version of society — the family — be reflective of that diversity with a man and woman as parents? How can a family be diverse if not for a mom and dad/male and female?
