It can't ever be done because it has never been done

Dinesh D'Souza says the answer to same-sex marriage is simple: "In issuing its ruling the California court appealed to the equal protection clause of the Fourteenth Amendment. The basic logic is that gays have a right to be treated like everyone else. But just like everyone else, gays do have the right to marry. They have the right to marry adult members of the opposite sex! What gay activists want is something else: the right to marry members of the same sex. This is not a right currently enjoyed by anyone."

As Balzac wrote, the law in its magnificent equality forbids the rich and the poor alike from sleeping under bridges.
