I found this blog with its attendant argument for legalizing polygamy. It is written from the perspective of a black male born in Nigeria and familiar with African tradition and also Muslim beliefs. Apparently he has researched Mormonism as well and has some interesting insights and arguments for legalization.
I find it interesting that opinions on conjugal socialization are fast evolving toward a more liberal stance. Freedom of choice regarding consenting adult relationships is the new trend in our modern world.
