SCOTUS has NEVER used the words, marriage is defined as a "Union between 1 man and 1 woman"........now, it may be true that they intend it to mean that, but they have NEVER specifically used those words or that language!!!<quoted text>
The issue is not "marriage", the issue is the definition of "marriage". In not ONE instance has the SCOTUS ever claimed anything other than the Union of a man and a woman to be a marriage. Could that definition change? Sure, but the question we really should ask ourselves is- do we want a federal court which lacks the authority of the Constitution to define marriage to make that decision?
Remember, they are also going to hear the DOMA case, which specifically was decided based on the premise that the regulation and definition of marriage rested with the State.
Actually DOMA has several sections and at the moment, only Section 3 is the one being challenged, but that does not mean that SCOTUS could not include Section 2 as well or wipe out DOMA all together.....but that is just speculation on my part......but Section 3 will be at the heart of their ruling!!!
