This man has long been an advocate for promoting traditional family values. He is quoted as saying "any male who doesn't support his children is a bum." He strongly criticizes sex outside of marriage. However, apparently, adultery is considered a family value by this man.
Family values are a belief by conservatives to include the nuclear family essential to the definition. The nuclear family is defined here as a household with father, mother and their children only. It specifically does not include grandparents, parent's siblings, step-children, and other such people. This would be known as the extended family.
If the nuclear family is a key factor in the opposition to same-sex marriage, then consider that the nuclear family is among the minority of family structures in the United States. When you look at households in the U.S. that are blended families, single-parent families, married couples without children, unmarried couples with children, and same-sex couples with children, the numbers amount to 75.9% of households (in 2005). While the nuclear family amounts to only 24.1%, the argument for an ideology that supports traditional morality begins to lose significance.
Family values embraces so much more than simply having a father, mother and their children in a home. It includes all who want loving, committed relationships within the family structure. Imparting values of honesty, trust, hope, fairness, truth, and the list goes on. When the right wing recognizes what hypocrisy exists in their cause, perhaps they will come to perceive the gay rights movement as supporters of nuclear families as well as other family structures that provide for the well-being of those in the home.
