I’m a little disappointed with the editorial or commentary. It is a non sequitur to compare no fault divorce with a same sex marriage relationship. In the divorce situation the parents of the child are separated so that the child does not have the full support of both parents; however, it does not follow that in a same sex relationship the child would not have the support of both partners.
I agree that no fault did not prove to be a panacea but I don’t know that if no fault laws had not been adopted the divorces would not have occurred anyway. This was a social upheaval that included the Church (at least where I was practicing) granting annulments in great numbers and as a matter of course.
I’m not convinced that a child in a same sex relationship with two involved parents would be worse off than a child of divorced parents where one parent was burdened with most of the care because the other chooses not to be involved.
I also question the observation that marriage has always been seen as consisting of one man and one woman. Patriarchs of the old testament had multiple wives, (Solomon had over 600 I think) in much of Africa men can have multiple wives, as is true in places in the East and Middle East. I do know that in the west the law favored marriage between one man and one woman because of issues concerning property rights.
