Polygamy more justified than same sex marriage?

Some free campaign advice from me.

If one of your major arguments against same sex marriage is that it will lead to polygamous marriage also being made legal, it’s not a great idea to state that polygamy is more justified than same sex marriage, as a natural institution.

Interesting of the three sorts of polygamy, polygyny is most common – a man with multiple wives. As Liz points out it is already legal in around 60 countries. Polyandry is not really legal anywhere and exists in a just a few far flung places.

Also of interest is that the Nazis looked at making polygyny legal because WWII killed so many men. Their reasoning was that with such a shortage of men, some men have to have multiple wives so that all German women could have children.
