I just love that particular line.
Aside from that, I just think that the basic definitions of terms are an aspect of this that the courts are choosing to ignore in this entire argument.
"MARRIAGE" - the union of a man and woman. Anything else (as the dictionary is even wrestling with) may be considered "similar" in some respects, but it's still different.
Apples and oranges are both example of fruit, but apples are not oranges.
I could argue this all day on Biblical grounds, but since the courts won't, I'm going for word definitions... which is what law is usually all about.
Every single term associated with marriage requires the union to be between a man and a woman.
Nuptials.
Couple.
Matrimony.
Union.
Wedding.
Connubial.
Betroth.
Bridal.
Monogamy.
And the list goes on and on.
If you study the etymology of each word, the union between a man and a woman is required.
