Mike, I think that train has already left the station (the latest pew research poll now puts support for same-sex marriage at 62% and, I suspect this support will continue to grow). Besides, if it were to change as you outline, it would't be something I would be able to support, as the only part of "separate but equal" that works is the "separate" part. The "equal" part repeatedly remained elusive.  This causes a violation of the equal protection clause. Hence, we have marriage equality.
