There isn't a clear line as to what constitutes "conversion" therapy and what doesn't, so you could have the courts defining what is and isn't allowed to be talked about in a way that goes beyond traditional malpractice law.
Is there anything currently stopping malpractice suits to be brought against abusive conversion therapy practices?
