Nope, cant support that but that is likely because I have no idea what you are trying to state here3) Individuals being married to no one
What the heck is a marriage to no one??? Last I checked, you cannot enter into a legal contract with yourself
Because marriage is not just a contract between two people. Which, BTW, I actually support, marriage being a contract between two people. Or three, or two people of the same sex. Once you get government out of it, you are free to make the contract you want with the participants you want and then it's nobody's business if you're two men or three or whatever.
However, marriage also comes with government perks. It is those perks I'm referring to. If you believe that gay marriage restriction violates equal protection, then denying the rights of marriage to individual citizens is even more so. Steve is married, Joe is not, they aren't equal under the law.
