IMO, being of the same gender is not properly some "unique disqalifying factor". As the child of a longterm but essentially loveless heterosexual marriage, I can say that there'd properly be other reasons to prohibit a marriage, or for a government to order one dissolved. (Maybe all
marriages should need 2B renewed every 10 years or so).
And I'd guess that parents who are heavy smokers (and-or drunks) can damage kids more than another couple free of those vices, who happen 2B of the same gender. I also have no specific objection to group marriages among consenting adults, FWIW. And a traditional nuclear family is not necessarily
the best place for a child.
But the LA mall owner who banned Manny Pacquiao
for being intolerant on this is being quite intolerant himself (like the politicians who wanted to ban Chik-Fil-A from opening in their cities last year). Again re. the last point, I'm all for the right to voluntarily boycott CFA, or any other business ppl find morally objectionable.
FWIW, I haven't voted (and won't vote) in this poll, because it implies a greater role for government in what a relationship is defined as than I think is proper.
Things like next-of-kin status could be determined in other ways.
