I'll be honest. I've never really understood the problem with polygamy. The usual arguments against are couched in terms of inevitible coercion and abuse of young women. My opinion has always been that laws already exist to address those issues. Why not punish actual crime instead of crime that is only in theory?
I will admit that Jonathan Rauch is changing my mind.
I strongly encourage you to read his fascinating article One Man, Many Wives, Big Problems.
I never would have thought of the surplus males problem. It's a good example of why political absolutes, in this case libertarian and social liberal, must be measured against reality.
