I'm cautiously optimistic.
As I understand it, marriage is a state responsibility. But maybe Washington can repeal DOMA.
In Canada, "gay rights" aren't protected under the Charter of Rights in the Constitution. But the Supreme Court made a ruling that basically said discrimination is discrimination. Maybe courts in the U.S. will make similar rulings.
I remember Proposition 8. And wasn't there some kind of ballot initiative on same-sex marriage in North Carolina? That's just wrong. It's basically taking away rights by popular vote. If that was okay, there would still be segretation in the Deep South.
