Is the “
myopic view of an adolescent” now a term of endearment? Somehow I missed that.
Fornication is simply sex between non-married people. And the
marriage paper does not add anything to the act or its consequences. Yes, whatever two or more loving people do in the privacy of their home (or in any private situation) is none of your business. Since the formal marriage is barely a few thousand years old, every sexual act before that was a “fornication”.
In simple tribal arrangements, even today there is no “marriage”. The children were (are) raised by the tribe, and if one or both of the biological parents dies, the whole family or tribe takes over the role of parenthood. A much healthier arrangement, especially for the development of the children. So you should learn about reality, before accusing others.
The concept of marriage has very little to do with biology, it was invented as a social arrangement, especially to preserve (or extend) the fortune of the family. It has gone through many changes, and will continue to do so. Morgantic marriages, polyamorous relationships, polygamy or polyandry all have their day under the Sun.
Whatever a society declares to be a “marriage”, it will become a de-facto marriage.
