"you build a new institution with it's own meaning, which is what you're trying to do anyway..." But you miss the point. Any new institution would lack all the history and meaning that is attached to the old one. That's what we want access to. The same institution that everyone else has had access to for centuries, and as such has built up meaning, and positive connotations, and legitimacy. A brand new institution lacks all that, and is, therefore a setback, rather than a step forward. And with full marriage equality available in Argentina, Belgium, Canada, Iceland, the Netherlands, Norway, Portugal, Spain, South Africa and Sweden, as well as Connecticut, Iowa, Massachusetts, New Hampshire, New York and Vermont, suddenly taking it away from the Americans who already enjoy marriage equality and asking American LGBTQ people to suddenly accept some other status is a pretty bitter pill to swallow. If this solution was ever going to be implemented, the time has passed.
