We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
"Normal", likewise "deviant", should probably be saved for statistical pronouncments. "Normal" is measured by mean, median, mode, and standard deviation, not by goodness/badness/rightness/wrongness. By statistics in the U.S. polyamory, polygamy, etc. are relatively rare. "You cud look it up!"
I don't believe that '1 in 5 Americans' has experimented with this, until I see how the question was asked. It's like the same old loaded statistic about how many gay people are running around loose, it was eventually shown to be bogus shock journalism.
But: How does this arrangement benefit the woman? Although the article is careful not to describe the distribution of sexes in these relationships, it seems implied that conventional polygamy is the norm (if that word can be used in this situation). Is this a case of the man's measure of success in life, or a case of the women's sharing of a man as a last resort? Who knows, or cares? They're needy attention hogs, as the picture makes abundantly clear.
They seem stuck trying to shock all the squares, but the squares have long since moved on. Nothing personal, but you don't deserve special treatment in the community with laws you can call your own. Get on with it!
Anything other than a man and a woman is a deviant marriage. Look at polygamous marriage. In Muslim cultures, such women are nothing more than brood mares. She has no right to property, because she is property. Her children are not even her own. Her life is often, depending on the Muslim country, perpetual house arrest and segregation. Under a tarp.
Look at homosexual marriages. Because they cannot produce children, they must often rent a womb. It's all rainbows and skittles until the child starts asking about mommy. Same with lesbians. Imagine being told your dad's a turkey baster.
The worst of the deviants is the Welfare Queen. She brings many children, by many different men, into the world without the provision and guidance of the fathers. They don't provide or raise the children they create because the State, the almighty State gives just enough money for Mama to sell her EBT funds for half the value so Baby Mama can get cash. The kids become savages, and either die violent deaths, go to jail, or become parents by the age of 12.
The concept of committed-for-life monogamy did not exist until the advent of Christianity and the teachings of the New Testament. Now that Christian ethics are being discarded, we are just going back to what was the norm before, and what has always been the norm in the non-Christian world.
"It seems to work out for some Mormons and many Moslems."
I can't speak for the Mormons, but I used to live in a Muslim country and I can tell you that polygamy is a miserable institution.
Most of the polygamous households I saw were filled with envy, bitterness, and vicious competition for the man's attention. Not happy places, not content, and not fair - the first wife would hog the resources. The only reason the women put up with it is because they felt like they had no other options. An emotionally toxic institution.
