Just gonna repost what I said on the other sub:

Eh, I'm personally fine with both but you do have a point with:

Forty or fifty years ago, "marriage equality" would probably be taken to mean the legalization of interracial marriages. In another decade or two, it will probably be taken to mean the legalization of polygamous marriages

Although, I do think it depends on the context. If I'm reading this correctly, if we're on the discussion of LGB then I think it would be fine to say "marriage equality." But, if we were just talking about anything and brought up marriage equality, then it could be confusing since it could mean anything! Are we talking issues relating to same sex marriage? Polygamous marriage? So yeah. I think it depends. Especially if there's different groups going about marriage equality at the same time.

The other reason that I prefer "same-sex marriage" is that "marriage equality" is morally-laden. I generally don't care for morally-laden terminology, since it tends to unnecessarily hinder discussion between people who aren't like-minded.

Anyone willing to explaing this bit? I never thought that "marriage equality" was considered morally-laden.
