Kudos to Utah based Federal Judge Robert J. Shelby for striking down that state's ban on gay marriage. http://en.m.wikipedia.org/wiki/Same-sex_marriage_in_Utah
Curiously though this decision may have an impact on another aspect of marriage practice for which the State is even more famous - the historical practice of polygamy.
Aside from the completely evil practices of pedophillic sexual slavery engendered commonly within polygamy is there any difference, fundamentally, between that practice and gay marriage? My answer, very clearly, is no. Both involve non-typical forms of marriage between consenting adults, do they not?
And, FWIW, it would also be completely legal to establish a contractual relationship outside of civil marriage laws between multiple individuals, would it not?
