Robert H. Knight was a draftsman of the federal Defense of Marriage Act, the current law that defines marriage as the union of one man and one woman for all federal purposes and allows states to resist demands to recognize counterfeit “marriage” licenses.

Knight is director of the Culture & Family Institute, an affiliate of Concerned Women for America. An ardent opponent of "gay marriage", he argues that:

  • Giving "gay" relationships marital status will destroy marriage.
  • Other groups, such as bisexuals and bigamists, will demand the right to redefine marriage to suit their own proclivities. Once the standard of one-man, one-woman marriage is broken, there is no logical stopping point.
