This is not Plessy v. Ferguson
The Supreme Court created new rights with its decision in a very real sense. Prior to their it, no one was being denied their right to marriage. Homosexuals had the right to marry just like everybody else. A gay man had the right to marry a woman and a gay woman had the right to marry a man. On the other side of things, as a straight man, I had not the right to marry another man. There was absolutely no discrimination here.
Moving on...
There will be one final chance to reverse the decision after the 2016 Elections. The Republicans would probably have to win complete control of Congress of at least 38 State Legislatures in order to call a national convention. It could then be proposed to amend the constitution to define marriage as between a man and a woman. If 38 of 50 state legislatures approve the amendment; same-sex marriage becomes unconstitutional. Abortion and no-fault divorce could also be addressed at such a convention, though I doubt that conservatives are bold enough to do so. I have my doubts as to whether or not they are willing to call a national convention, but at least they're talking about it in some circles. Personally, I believe that it is the only chance of success that we have.
Do I expect any of it to happen? Absolutely not. Conservatives in this country had indeed surrendered, but they did so, in very real sense, years ago. All that remains is just for show.
