We need this amendment because while Forty-three states have statutes defining marriage to one man and one woman... activist liberal judges (most recently in Georgia) have been saying those statutes are unconstitutional.
So we need to make the definition of traditional marriage part of our national Constitution.
My point was that you cannot put traditional marriage into the Constitution, or anywhere else, because people overwhelmingly favor easy divorce and decriminalization of adultery.
Calling what's left after you allow unilateral divorce and don't punish adultery "traditional marriage" is really dishonest. There's nothing traditional about it at all.
