I dont' know if I said that originally. But that is exactly what my opinion is on the issue. EVERYTHING should be a civil union. And then, if you are married by a religious person, then it would be 'marriage'.
The problem is that people would be so outraged that it'll never work. Frankly, it's kind of sad. Marriage is simply a specific religious term for a civil union.
My marriage to my wife is no different than Frank's civil union to Steve and if civil unions had 100% of the same rights that marriage had, I think things would be pretty simple.
I also think gay marriage advocates have done a terrible job framing the issue. They should have framed it as a fight for civil unions with 100% of the benefits of marriage (and divorce) rather than the specific fight for "Gay Marriage". That has set back the battle for 100% rights for a while.
