I think polygamy is a different scenario, since it doesn’t have a huge fan base on the left like sodomy and lesbianism do. It is a feature of certain patriarchal cultural lifestyles that don’t have nearly the leverage this does. But I look for mandatory same-sex weddings in all 50 states and DC by the end of 2015 or sooner.
This country really needs a revolution.
The polygamy wall will be breached as a result of legal action by muslims, not from Mormon sects. The dhimmi hordes will use the same arguments, “consenting adults”, “loving relationships”, “akin to slavery”, etc., etc.
