Groups such as Focus on the Family are not "family" organizations, even though they certainly claim to be.
Without a doubt, they would dispute my statement, but you see, their claim can be proved false simply by analyzing their approach to family life.
Are groups such as these intent on preserving family life as it is - or are they intent on enforcing an unrealistic ideal which happens to suit their personal religious "world view"? Were their claim true, would they not be nurturing the families that happen to exist out there, supporting them, instead of cracking down on family types they happen to dislike, refuse to recognize as families, and drive wedges between family members?
