You are simply wrong Kurt.
Marriage is not the issue. Anyone can marry anyone else today as in the past. What is at issue is sanctioning single gender relationships with a license and awarding benefits to single gender (or other, not traditional relationships).
40 states have constitutional provisions prohibiting single gender marriage licensure. The federal government has DOMA, which recognizes that Americans seek to reward only male/female unions.
It is not over.
Marry whoever you want (and as many people as you want of any gender whatsoever), but don't expect to receive a reward for that behavior or find that others celebrate that behavior with you.
