In his otherwise quite good
analysis of the gay marriage debate, in USA Today, law
professor Jonathan Turley is also supportive of polygamy:
Whether damnation awaits monogamists or polygamists or same-sex couples is a matter between citizens and their respective faiths. The government should address that aspect of marriage that concerns its insular needs: confirming the legal obligations of consenting adults. As for our politicians, there are levees to be rebuilt, corruption to end and wars to win.
Is this a harbinger of where liberal, or even libertarian,
opinion feels compelled to head?
