Odd that polygamy wasn’t first, ahead of homosexuality. Seems a whole lot more people are interested in trying ( or are practicing) plural (heterosexual) mating - than they are homosexual intercourse. And its possible to argue that the Biblical instruction or teaching against homosexual intercourse was set forth more vigorously than that dealing with polygamy. But yes, it’s likely we will witness a move in favor of legalizing polygamy now.
I am not saying I support it. One wife is enough to keep up with. ;)
