I think I'd go with same-sex marriage myself. "Marriage Equality" could mean anything and nothing at the same time. It is really ill-defined, like the label, "Queer". And similiar to that label, I wouldn't be surprised if people also took advantage of the ambiguity to push their own unrelated agenda. I have never used and probably will never use the term "Marriage Equality" because I don't know what it means, when another more descriptive and less "inclusive" term exists. And if there's one thing I learned from this TQ++ mess, is that the devil's in the inclusions.
