and do so consistently: "When you are defiantly challenged, win decisively." In The Strong-Willed Child, Dobson draws an analogy between the defiance of a family pet and that of a small child, and concludes that "just as surely as a dog will occasionally challenge the authority of his leaders, so will a little child—only more so" (emphasis in original). When asked "How long do you think a child should be allowed to cry after being punished? Is there a limit?" Dobson responded: Sociologists John Bartkowski and Christopher Ellison have stated that Dobson's views "diverge sharply from those recommended by contemporary mainstream experts" and are not based on any sort of empirical testing, but rather are nothing more than expressions of his religious doctrines of "biblical literalism and 'authority-mindedness. Views on tolerance and diversity In the winter of 2004-2005, the We Are Family Foundation sent American elementary schools approximately 60,000 copies of a free DVD using popular cartoon characters (especially SpongeBob SquarePants) to "promote tolerance and diversity." Dobson contended that "tolerance" and "diversity" are "buzzwords" that the We Are Family Foundation misused as part of a "hidden agenda" to promote homosexuality. Kate Zernik noted Dobson asserting: "tolerance and its first cousin, diversity, 'are almost always buzzwords for homosexual advocacy.'" He stated on the Focus on the Family website that "childhood symbols are apparently being hijacked to promote an agenda that involves teaching homosexual propaganda to children." He offered as evidence the association of many leading LGBT rights organizations, including GLAAD, GLSEN, HRC, and PFLAG, with the We Are Family Foundation as shown by links which he claims once existed on their website. The We Are Family Foundation countered that Dobson had mistaken their organization with "an unrelated Web site belonging to another group called 'We Are Family,' which supports gay youth." Dobson countered: In September 2005, Tolerance.org published a follow-up message advertising the DVD's continued availability, including We Are Family Foundation president Nancy Hunt's speculation that many of the DVDs may be "still sitting in boxes, unused, because of Dobson's vitriolic attack." Views on homosexuality Dobson believes that God defines marriage as between one man and one woman only and describes this as the central stabilizing institution of society. Dobson believes that any sexual activity outside of such a union—including homosexuality—cannot be approved by God. In Dobson's view, homosexuality results from influences in a child's environment rather than an inborn trait.
