There is no intellectual or legal basis to deny polygamy or gay marriage.
ONLY a constitutional amendment can stop this train...and I don't see that happening either.
The founders just didn't see this one coming.
The 1972 Gay Rights Platform....
7. Repeal of all laws governing the age of sexual consent. (1972 State-7)
8. Repeal of all legislative provisions that restrict the sex or number of persons entering into
a marriage unit; and the extension of legal benefits to all persons who cohabit regardless
of sex or numbers. (1972 State-8)
