Peter Sprigg, senior fellow for policy studies at the Christian conservative Family Research Council (FRC), used the death of actor-comedian Robin Williams to promote “ex-gay” therapy.

Such controversial therapies, which aim to alter a person's sexuality from gay to straight, have been outlawed in California and New Jersey among minors.

In a blog post published Monday, Sprigg compared Williams' struggles with addiction and depression to people struggling with their sexual orientation and asked why liberals aren't trying to “outlaw rehab.”

“I ask the question because such activists are trying to ban a form of mental health treatment – not drug and alcohol rehabilitation, but 'sexual orientation change efforts' (SOCE), also known as 'sexual reorientation therapy.' Such therapy involves assisting people with unwanted same-sex attractions to overcome them,” Sprigg wrote.

“Why would someone want to change their sexual orientation? Some such individuals are simply disillusioned by their experiences in homosexual relationships. Some have legitimate concern about the well-documented health problems associated with homosexual conduct (especially among men), such as high rates of sexually transmitted diseases, of which HIV/AIDS is only one example. Others may seek help in conforming their behavior and lifestyle to the teaching of the religious faith to which they are committed. Some may aspire to a traditional family life, raising children in a home with both their mother and father present.”

“Whatever the motivation, there are those who have simply made a choice to walk away from the homosexual lifestyle, without clinical help – much like how Robin Williams simply stopped using drugs and alcohol in the 1980’s. Others have sought professional help, perhaps at the urging of family members, in the form of 'sexual reorientation therapy' – much like when Williams entered a formal alcohol rehab program in 2006. Whether simply through personal development, religious counseling, or with the help of a licensed or unlicensed counselor, thousands (if not millions) of people have experienced significant changes in one or more of the elements of their sexual orientation (attractions, behavior, or self-identification),” he added.

In 2010, the Southern Poverty Law Center labeled FRC an anti-gay hate group.
