I refuse to purposely click on a CNN link. Cuckolding means that the wife is having illicit sex with another man, a maritital crime. The husband would not be participating. If CNNs idea that it's beneficial, and the husband is participating, then it's really sinful swinging that nasty perverts do. How is this beneficial?
That is your version of religion and morality. It is not everyone's. Don't impose your version onto others.
It is beneficial because all three parties get something out of it.
It is not your business to tell others what is beneficial to them.
. Well most people like to stick with what is proven to be a good thing, and to stay clear of the things in which are proven to be a bad thing, so if something is bad and it begins to invade the spaces of those whom know it's bad, then they want the same results that you espouse here. They want the bad to stay the Hell out of their space and lives in which they are raising their children in. Problem is that the bad can't stand that, because it can't do damage if told to get the Hell out of someone's space or face.
So then the bad go and aquire government to beat the good over the head with their bad in order to cause the submission of the good in order to then force the good to except the bad as something good.
