The first polygamy challenge is starting in Montana right now. The likely plaintiff was very clear why he and his two wives were doing it: the Supreme Court opinion.
They've been waiting for the homos to open the door. Heck, they were probably half of the people at the homo protests - not because they care about the homos - but because the homos are doing all the work and the polygamists can just demand their rights for free.
Actually, the polygamists were pretty smart to keep quiet and wait it out. Now all they have to do is call for THEIR equal right to marry who ever they "love". Who can argue against them now?
