The Constitution doesn't mention many, many things. It doesn't mention cars, computers, or jets. And yet aspects of each one of these items can be argued before the Supreme Court.<quoted text>
OK, let's first address that part of the Constitution that even mentions definition of marriage. Find that for me, would you?
Then, let's analyze their meanings and intentions, shall we? Then, we'll address the part that states that a SCOTUS decision can overrule the part of the document that empowers them to act, at all. The part that says that SCOTUS can nullify any part of the C they they find....inconvenient.
Problem is that the C doesn't have any provision for "interpretation" of hard coded items.
Marriage of interracial couples was argued before the Supreme Court. Polygamy was argued before the Supreme Court. And now Same-Sex Marriage has been argued before the Supreme Court.
The Supreme Court has not nullified anything that exists in the Constitution--at least not with the Proposition 8 case or the DOMA case.
Amendments have been made to the Constitution. These amendments were added according to the process provided by the original Constitution.
Based on the Supreme Court's interpretation of the Fifth Amendment, Section 3 of DOMA was found to be Unconstitutional. This allows married Same-Sex couples to qualify for Federal Benefits in those states that currently (or in the future) recognizes Same-Sex marriage.
Now I realize that this flies in your face. You don't like it. But your only recourse is to start your own movement, find your own attorneys, fight your own court cases and eventually bring your own arguments before the Supreme Court. Good luck with that.
