The Marriage War.

A Washington group is using a peculiar legal tactic to defeat other restrictive laws on marriage by taking those restrictions to their logical ends. If marriage exists solely for procreation, then the legality of a marriage should be contingent upon that condition. And so, this group has proposed a state initiative to invalidate marriages that don't produce offspring. No kids = no marriage.

It won't pass, but it does make a point. If gays can't marry because marriage is for procreation, then that must legally apply to everybody. Old people, infertile people, and people who want each other but not kids must also be forbidden the sacred bond of matrimony.
