Proposition 8 defense: Marriage exists for -- what?

The arguments made by Proposition 8's defenders in the federal court trial fell apart when even their own experts were unable to articulate how, for example, same-sex marriage would in any way harm opposite-sex marriage. Apparently feeling a little low on reasonable explanations for why gay and lesbian couples should be prohibited from marrying, lawyers added a new twist into their argument before the U.S. Supreme Court, and this one might be the strangest yet -- and the most easily attacked.
