Supposedly the Defense of Marriage Act gave states the right to not acknowledge gay marriages in other states if they don’t wish to do so.
But that won’t hold up for long. We need it in the US Constitution but won’t get it any time soon with the congress we have yet.
With a Constitutional Amendment, thirteen states can keep any Amendment from being enacted. By the time one would pass the House and the Senate, we will have thirteen states that allow same-sex marriage explicitly.
We couldn't get anywhere near a Constitutional amendment with any congress we had. It's a foregone conclusion, in my opinion, that we've seen the most conservative congresses that we'll ever see - only RINO's and liberals in the future - unless a major revolution occurs, and that's not likely to be a purely "conservative" revolution.
The only other hope I see on the horizon is a real spiritual awakening and true, spirit-wrought Christian revival - which would restore much of the lost innocence of conscience that can't be realized any other way. But I can't see that we even want this.
