Well, it's really going to depend on what you want out of the union. Do you want people to know that you're together? ****, then just get a ring and parade it around! Who needs the red tape? Do you want the church to recognize it? Good luck, but chances are low, and it's really no business but the church's how they run things. Do you want it recognized by the government? Well, geez, just draw up a contract that consolidates your assets and gives you and your partner mutual power of attorney. Get some witnesses and off you go. As long as you've got a lawyer who's down with it, you can get him to draw up a contract that is verbatim a marriage license in all but name.
The whole gay marriage issue is a bizarre obsession with a word that has been laden with so many strange and useless meanings over the years that people have forgotten what it should really be about. For them, their life isn't complete without that word, and frankly, the word is worthless. If you and your partner care for each other, and are committed to each other, then all you really need is the legal recognition to act as a couple. Why obsess over the word?
If people still want the word, I think they should have it. I just think wanting it and not seeing what it means (or even trying to attach to it a meaning that it doesn't have) is immature.
