I addressed the same-sex sibling issue in #9314 on 4 Sept.<quoted text>
There's also no reason why siblings, at least same sex, can be spouses, or three people can't be spouses.
Plural marriages has also been address ad nauseum. It is not my issue. If those seeking such legal marriages wish to petition either their state legislature or the courts to seek redress, they are more than free to do so. More than two spouses would need a total revamp of the laws governing married couples however (something that did not have to happen when same-sex couples began marrying.).
The key word in all of this is SPOUSE. Not husband or wife. Did you ever find any law that treats the 'husband' or 'wife' differently?
Just because the phrase 'I now pronounce you husband and wife' is not used in same-sex marriages does not make those marriages any different or less legal than marriages that happen to use the phrase.
