Conversion Therapy is Child Abuse
And I would support legislation allowing victims of this child abuse to sue their abusers for damages, which would include compensation for therapy for post-traumatic stress and other harms.
Rely on the science. To force children -- or really anyone -- against their will to do something that is impossible is, ipso facto, traumatizing.
The torture can be physical, mental, emotional, or psychological. But torture it is. And any clinician who does so should not only lose their license but should also suffer civil penalties (and criminal ones, if physical torture is used).
