We're falling into the premise that gay marriage is even possible. Marriage requires two different units, not the same one in duplicate. Two flavors can marry, or three, but not two of the same flavor. Think about that for just a minute. Then think about two brides or two grooms. That may be the dumbest sight in the world. These people are looking to marry two brides? Even that causes semantic problems, and in the homosexual world, they consider one a husband, and the other a wife. Why would they not dress that way to marry.
Obama must have the fallacious idea that we care what B-HO thinks, or that he does at all.
