I don't think that the government should call it marriage. I can think of several situations where people living together should enjoy the same rights as people who are married. I've known many people who live with others for all sorts of reasons. I think that you should be able to go down the government office, file a paper declaring yourselves a household, and that should be it. Then you have the same rights for survivorship, custody, inheritance, health care... whatever.
As for the marriage thing, you get married where you want, by someone you like... in your church... by a favorite clergy... or justice of the peace. Then you go down and file your household declaration.
Failing that, which will NEVER happen, anyone should be able to marry someone else. Why oh why does anyone else care? The world will not end. Hopefully we'll get this behind us here in the states within the next decade. I'm pretty sure that it will happen. Then we can move on to the next social crisis.
