The simple truth that I see here is, opinions =/= facts.A sect of the Mormon faith believes that having multiple and underage wives is blessed by god, even though it is not tolerated by the laws or morals of society.
Every young mans dream is having a three way with two hot babes to brag to his buddies about but wouldn't think of telling total strangers or even his family.
Everyday men and women get super freaky with their lover in the privacy of their homes, cars or wherever, doing things their mother told them never to do.
Couples you would never suspect, swing at parties on weekends after dropping off the kids at grandmas house and nobody is the wiser on monday morning.
Most of us are guilty of something we don't dare talk about in public because no matter how innocent it seems to us we're aware that others might judge us immoral.
The morality of what people do in private is only relevant to the participants and even though there are others who might be offended by those things, it is none of their business.
That is as long as we keep our dirty little secrets in our own bedrooms, but when we drag them into the public forum and demand acceptance, it becomes society's problem.
Then we all must deal with the legal and social problems that arise like marriage, adoption, military, public benefits, offensive actions and behavior, etc-etc-etc__The list is endless.
And then we must explain to little billy and susie why bobby has two daddies, mr smith use to be miss smith, and and the two ladies next door are necking on the front porch, etc-etc yet again.
The simple truth of the matter is, society will fair much better if we remain ignorant of each others perversions and believing that all of our neighbors are moral upstanding citizens of the community.
