It is not a necessity, whether a couple is married or not. Children can be and have been raised by same sex parents. Many studies of children raised by same sex parents have shown them to be just about the same as children raised by opposite sex parents in terms of self-esteem, gender identity, and general emotional well-being.
You are talking about events outside marriage. Wolves have successfully raised children. Should we have wolf-marriage now too because of that false premise? Obviously not.
Pay attention here: THE REASON THE MARRIAGE CONTRACT WAS INVENTED OVER A THOUSAND YEARS AGO WAS TO PROVIDE BOTH A MOTHER AND FATHER TO CHILDREN IN THE SAME HOME AS THE ADULTS. Since both boys and girls arrive as children in a married home, it is vital that both role models be present. If they're not, the Prince's Trust survey 2010
PRINCE'S TRUST 2010 YOUTH INDEX SURVEY and the amicus briefs linked in my signature say that the lack of the gender-specific parental role model (the epitome of role models) HURTS CHILDREN.
That contractual provision of both mother and father innate to the marriage contract since its inception,for children, was just removed, without their consent, and to their detriment. And that, of course, is forbidden under necessities, infants and contract law. Children not only did not disaffirm the marriage contract of mother/father, they were barred from having a voice at Obergefell. All proposed contractual revisions demand as a matter of deep established law that all parties to that contract, written or implied, MUST have representation at the proposed revision Hearing. That simply didn't happen. As I've said, Obergefell therefore was a mistrial. You can't have a hearing on a matter without all parties to that matter having representation or being present at the Hearing. Good luck challenging THAT one with case law
I see you are backing down, unlike your cohorts here, on claiming that children somehow aren't implicit sharers of the marriage contract. Good. Baby steps...
