Polygamy is a larger step than gay marriage and won't have the support of many people who currently support gay marriage. Nevertheless it will slowly gain acceptance. Right now it's just getting through decriminalization stage. It's up to its adherents to fight for it.

Quote:
Before this opinion, it was a crime for polygamists to live, as do the Browns, in a plural family. After the opinion, it is legal. This is precisely what occurred in Lawrence v. Texas where homosexual unions were a crime but then became legal when the Texas law was struck down. This decision legalizes tens of thousands of polygamous families who will no longer been viewed as criminal enterprises. They will be allowed to be open plural families. They are now legal relationships. Legality of polygamy is entirely different from recognition of plural marriages just as the legality of homosexual relations is different from the recognition of same-sex marriage.


"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
