I'm surprised this is occurring in Iowa.  California, Massachusetts, and even Washington state.  But Iowa?  Apparently the Iowa constitution looks friendly to the pursuit of gay marriage via the courts. 

DES MOINES -- A gay rights group filed a lawsuit on behalf of six gay and lesbian couples Tuesday in Polk County District Court, asking for the right to marry for same-sex couples.

Lambda Legal, which has spearheaded the same-sex marriage drive across the country, said it wants full recognition of the civil rights of same-sex couples.

I'm all for gay marriage but I'm not comfortable with it being implemented via the courts.  I would prefer that it happen legislatively or via a popular vote of the people.  Particularly when it is indisputable that the original intent of the constitution or law being utilized was that marriage only be for men and women.  The original intent may have been wrong but there is a procedure for changing it that should be utilized.  Changing the meaning via the courts is just wrong.  Freedom of the press could just as easily come to mean the government printing office has the freedom to print the news but private or corporate "press" is not.  You think it couldn't happen?  Look at what has happened with the Second Amendment.
