We May as Well Let People Marry Dogs!

Other dangers exist. If marriage can be redefined so that it no longer means a man and a woman but two men or two women, why stop there? Why not allow three men or a woman and two men to constitute a marriage, if they pledge their fidelity to one another? It’s Madness!"

Other dangers exist. If voting privileges can be redefined so that a black man vote equals a white man vote, why stop there? Why not allow a woman vote to equal a man’s? It’s Madness!"
-The Average Opinion in the 1800’s

Same reasoning, same ignorance, different bigotry.

Marriage is a life long promise/commitment between consenting adults to take care of each other.  We should not care about how many or what sex.  Consenting is the key word there.  That is a great starting point when defining laws like this.  This stupid argument about people eventually marrying dogs, cats or children stops dead in its tracks when you point out the part about all parties involved consenting in the process.  Polygamy however...well I know most people have a problem with it.  But why?  I've never heard a universally moral argument against it.
