Indiana's ban on gay marriage wasn't just struck down, it was savagely mocked by three federal judges

From the unanimous decision from the Seventh U.S. Circuit Court of Appeals, which also struck down Wisconsin's ban, written by three judges appointed by Clinton, Obama and Reagan:

     Indiana’s government thinks that straight couples tend to be sexually irresponsible, producing unwanted children by the carload, and so must be pressured (in the form of governmental encouragement of marriage through a combination of sticks and carrots) to marry, but that gay couples, unable as they are to produce children wanted or unwanted, are model parents—model citizens really—so have no need for marriage. Heterosexuals get drunk and pregnant, producing unwanted children; their reward is to be allowed to marry.
     Homosexual couples do not produce unwanted children; their reward is to be denied the right to marry. Go figure.
     ...The state should want homosexual couples who adopt children—as, to repeat, they are permitted to do—to be married, if it is serious in arguing that the only governmental interest in marriage derives from the problem of accidental births. (We doubt that it is serious.)
