No, but he made one good prediction. A Utah couple is challenging the state's law against bigamy based on the Lawrence v. Texas decision, which ruled that the Texas anti-sodomy law was unconstitutional. In addition, I imagine a religious freedom argument applies here, since Mormonism used to embrace the practice. Look for a Muslim to make the same challenge.
Polygamy has been practiced in a many cultures, including the one from which Christianity sprang. If you are a multi-culti you have to support it.
