It would be easier and more effective to just get rid of the word "marriage" to describe our unions, and just call everything civil unions or some such thing.
The word "marriage" cannot mean anything other than heterosexual unity. "Gay marriage" is technically incorrect, and untrue to the etemology of the word, and historical and legal usage. That's one reason why Obama was able to say that he doesn't want to redefine marriage, because he can't. It's like the court ruling that a circle must have three sides, or a triangle have four corners.
I have to respectfully disagree. Women in marriages are still called "wives." Now how has THAT term been re-defined? Terms like property procurement and dowries come to mind here...........
Nowadays, a wife is more of a companion, but married women never changed the title.
