Outstanding piece by the great Razib on the Texas mess. An excerpt:
The emblematic violation of those norms was of course plural marriage, polygyny. I don't think that plural marriage is wrong like murder is wrong, but the social dynamics which emerge from its ubiquitous practice among the FLDS are well known, and I am skeptical that the practice is conducive to the perpetuation of a bourgeois republic. Even within the Muslim world modernizers are very critical of polygyny because of the familial destabilization it portends. In a world where time is finite one can make quick back of the envelope inferences about the effect upon parental inputs in a situation where one man fathers dozens of children with multiple wives.
