For Christians and Muslims, marriage is indeed a religious institution. But if we take away the religious aspect for the sake of argument, we’ll find that secular cultures have recognized and promoted marriage for centuries. They never did so for same-sex couples. Why not? Because procreation, virginity, fornication, adultery, dowries, and consumation of a marriage contract were irrelevant for same-sex couples.
Sorry, lj. I didn’t mean to copy you on that.
Marriage is Natural Law. Even many animals mate for life - many birds, for instance.
It’s Mother Nature. They want to overturn the laws of nature and whenever that is attempted, the results are never pretty.
