Don Lee makes a case that
"Polygamy is more Ethical than Monogamy.”
He explains that professing monogamy isn’t always matched with actual monogamy.
In Western culture this is generally referred to as either "family friend" or "serial monogamy", neither of which are true monogamy. While being legally married, approximately 80% of all couples experience a sexual contact outside of marriage, and this remains the 2nd largest cause of classic divorce.
It may be
cited as a cause in a certain number of divorces, but in a good chunk of those cases, it is not the cause. It may be a symptom. Yes, there are some divorces in which cheating (a physical, emotional, or financial relationship with someone in violation of the agreement with the spouse) is the cause, but I think it is clear to less biased observers that the cheating is a
symptom of the real problem leading to the divorce.
The largest cause of divorce is loss of income, itself a revealing indicator of what Western Marriage is really all about.
Moral monogamy is "marriage until death" in most cultures. Legal monogamy is having only one legitimate spouse. These are in no way similar concepts, and in practice are quite diverse. Legally, you can be "monogamous" about nine or ten times, and some people have been married more than a dozen times.
In general (prostitution and consanguineous sex being generally illegal, and thus excluded) a married person having sex with someone other than his or her spouse is not criminalized in the US, though in a few states it can be subject to a lawsuit in civil court.
My point is not just that "serial monogamy" isn't really monogamy, and it isn't, but that many completely happy 30+ year marriages indulge in "private activities" which involve other people. Apart from the roughly 90 million Americans [almost one in three] who are members of sexually-themed clubs, or swingers, there is the harsh reality of cheating. 8.5 in 10 marriages experience infidelity according to most studies. The number ranges from 6 to 9 in 10 depending no the focal group, however the larger the group - the higher the ratio trends! Meaning, the likelihood that more people "cheat" is found to be more significant when studying larger groups.
As I have said before, actual monogamy is a minority behavior.
The chances of a successful marriage are less than 30% by most calculations, and those are odds I would not play even in Vegas.
This is where I think the writer gets it wrong, depending on how one defines “successful.” I suppose it is possible to say that if you exclude
all marriages that end in divorce, separation, estrangement, or otherwise experience significant trouble, no matter how long they lasted or what was accomplished during the marriage, you could arrive at this figure. Mostly, though, when emotionally healthy and mature people marry with no prior marriages or other significant baggage (prior children, large debts, serious criminal record, Anita Bryant record collection), the odds of it lasting until death are high. But you do have these people, especially a lot of these types who tend to be against marriage equality, who marry and divorce three or four times, skewing the odds.
