Conversion therapy should be banned to protect vulnerable young people from therapists who would lie to them, telling them that their sexual orientation is a mental illness. I knew a man through church who had been subjected to conversion therapy in his teens. Years later, he was still gay, and also chronically depressed. In fact, conversion therapy is linked to depression, low self-esteem, and even suicide. No therapist should be allowed to abuse patients with this a cruel and dangerous practice.
