I doubt if the state ever gives it up at this point, it provides too much influence over the culture. In my opinion, if modern trends continue, a bad influence. If I recall, even the soviets didn’t abolish their own state recognition of marriage, they just outlawed religious recognition (in their own minds) for a period of time. It’s been a while but I don’t think that lasted.
Then again, if you would have told someone about state recognized ‘gay marriage’ 30 years ago they would have thought you were absolutely whacked out. And that was never around in any sort of serious way before as far as I can tell. So as far as I know anything is possible at this point.

Read post 33, there is always a common definition of marriage, it isn’t something that just showed up when America was created.
