Judo politics and gay marriage

Some of you may recall that the Supreme Court here in Washington state upheld the state's ban on same-sex marriage back in July. Specifically, the majority opinion stated:

...the legislature was entitled to believe that limiting marriage to opposite-sex couples furthers procreation, essential to survivial of the human race, and furthers the well-being of children by encouraging families where children are reared in homes headed by the children's biological parents.

Recently, a group in favor of equal marriage rights launched I-957, the Defense of Marriage Initiative. I-957 applies the court's reasoning to heterosexual marriage; it would require all married couples to show evidence of procreation within three years or have their marriage automatically annulled. Couples from out of state would be required to provide proof within three years of moving to the state or have their marriages declared "unrecognized."

The goal, of course, is to point out the absurdity of the court's (and legislature's) reasoning by carrying it to its logical conclusion. This is the essence of judo politics -- turning the force of your opponent's strongest arguments against them.
