@wandeljw,
Ah, so.
I'll go with the aclu on this one.
Bunning, I remember him.
Me, I think of marriage as a carpet, very important in many cultures. Also, important legally in many cultures.
I had good friends who got married for tax reasons; it's been many years now.
My own view is that religious ceremony people should go for it. Me, I remember a photo I took of a bride and groom at the Campidoglio in Rome, she all dressed wonderfully. They were just leaving after signing in for the state ceremony.
Legal does matter, for most of us.
