While polygamy is not something I would every personally endorse or participate in, I don’t see how it is our business if everyone involved is consenting. Likewise, if a woman wishes to have more than one husband, it is not my business to dictate to the consenting parties that it not happen. Except for a marriage license, multiple people can already live as man and wives or wife and husbands – by cohabitation, pooling resources and living together. And it’s legal, except for the “license.”
Again, going to the most-cited moral authority, polygamy was favored in the bible and still practiced when the new testament was written. I won’t bore you with the countless citations. If you disagree that the bible did condone it, stop reading – there’s no point trying to get into your head.
Are there legal issues with having more than one spouse? Yes. Does it make it difficult to navigate with multiple spouses? Yes, of course. Given that our society is rife with failed marriages, open marriages, etc, how is it more reprehensible to have multiple spouses than to have an open marriage when 1 or both parties have active sex lives outside of the marriage. There are already people in your community with a wife and husband and mistresses. There are plural marriages, even if they are so defined in the spirit of the word rather than the legality of its implication.
Why do Americans think that we have the ability to allow or regulate polygamy when it is between consenting adults? Because that is what is beaten into our heads. We didn’t reach this state through logic and understanding.
We reached it because it is too different from the expected norm of society.
We routinely tolerate or idolize those who have multiple partners, whether through marriage or mistress, as the saying goes.
The hypocrisy is on our part for condemning it, especially those whose roots branch from traditional Christianity.
