I stated that much myself...
As for my reasons.... they would never be broadly accepted by the forum's liberals... pfffftttt... they would first have to believe that GOD existed in order to accept that He could be a unifying influence in the home; hence preventing their failure. Obviously not all heterosexual families fall in that category. And not all 'self-proclaimed Christian' families actually live by the Christian ideals either, which would make them just as susceptible to failure.... But that's another can of worms...

sexuals obviously couldn't fall in the first pool... hence the dilemma.
