I personally feel that the government should get out of the marraige business. I don't believe in tax breaks for married couples (and I'm married) or that there should be tax breaks for dependents.
I do believe that any couple or family can declare themselves a household when it comes to health insurance or legal issues.
When this thing comes up with any of my Mormon family, I ask: "Do you not think that gay people do not get married in their own churches?" The law will never prevent that. So why should it even try?
