Remember back when the whole homosexual marriage thing was being argued in the courts?
Remember how there were at least a few people who said that, should the court decide that changing the legal definition of marriage would open the door to other 'forms' of marriage - things like polygamy and polyandry and, perhaps, child-marriage and marrying animals or inanimate objects?
Remember when proponents of homosexual marriage assured everyone that that sort of thing would never, ever happen?
