Conversion "therapy" is nearly universally recoganized as harmful in the medical community. As somebody with a degree in Psychology, and who is about to start graduate school to become a therapist, I can absolutely tell you that research on these "therapy" techniques shows that they are incredibly harmful. Children exposed to sexuality conversion attempts suffer from higher rates of anxiety, depression, suicide, low self-esteem, and drug addiction. These symptoms are similar to those caused by physical child abuse.
Aditionally, minors can not realistically consent to these "treatments". First off, they are too young to give consent. Secondly, they are in a coercive circumstance because, in many cases, their families may disown them if they do not want to go through the therapy. A child who is being coerced can not legitimately give consent.
Please ban these practices from being used with children.
