The answer to this whole issue is simple. What has to happen is that the State will recognize what it calls "Civil Unions" whether they be between man and woman, woman and woman or mam and man. All divorce laws will apply to these people.

"Marriage" always was and still is an institution which comes out of religion. Thus if a particular religion does not allow "gay marriage" then gays will just have to go find some religion that does. Then they can have their religiou srvice and then go down to city hall to make it official --- or not --- depending on whether they are religious.

Same thing for straight people. They can go get "married" by the clerk of the court and also do it in Church.

The state would simply stop recognizing religious ceremonies as civil unions. Case closed.
