Ballot initiative would require married couples to "show proof of procreation"

Boing says there is a Ballot initiative would require married couples to "show proof of procreation". From the article:
The Washington Defense of Marriage Alliance seeks to defend equal marriage in this state by challenging the Washington Supreme Court’s ruling on Andersen v. King County. This decision, given in July 2006, declared that a “legitimate state interest” allows the Legislature to limit marriage to those couples able to have and raise children together. Because of this “legitimate state interest,” it is permissible to bar same-sex couples from legal marriage.
The only downside is "the Defense of Marriage Initiative would: ... require that couples married in Washington file proof of procreation within three years of the date of marriage or have their marriage automatically annulled..." What if I want to get married without children? Or worse . . . what if I can't have children?

On the other hand, many of the "marriage benefits" that this initiative would protect have to do with tax claims and insurance coverage having to do with starting a family and having kids, I assume. (Not that I'm an expert on legal marriage benefits.)

With that in mind, however, it's completely reasonable to assume that marriage benefits were designed for a family with children and would therefore have no place in homes where a couple is unable or unwilling to procreate. Taking those benefits away from everyone who doesn't intend to have kids, gay or straight, would probably take away much of the homosexual interest in marriage. This whole thing, however, doesn't account for adoption.

So the initiative has a few kinks to work out. We'll, no doubt, see where this goes.
