Agreed John. Government should only recognize civil unions, all of them, whether they be between man and woman, man and man, woman and woman, man and television, woman and shoes, etc etc etc. OK, just kidding about the TV and shoes..... but a legal agreement, with all the rights and advantages.
Marriage is a religious thing, and not owned by Christianity as there were marriages being performed by religious groups for thousands of years before Christianity was ever thought of... so don't give me that "the bible says" stuff.
Keep the marriage in the church, temple, mosque, grass hut, etc. Civil unions only concern the government, and they're at the courthouse.
That'd solve a lot of problems.
