Sexual orientation change efforts use shame, extreme conformism, false accusations about behavior, and ostracism to cause decreased self-esteem, drug abuse, depression, and suicide.
It is a sin for "ex-gay" and "conversion" therapists to deceive and abuse youths and their parents with such abuses, all of which reinforce the depression and addictive behavior that these fraudulent therapies falsely claim to cure.
Conversion therapy exploits parents both financially and emotionally, causing them to spend thousands of dollars on treatment that makes their loved ones sicker.
Mental health professionals should provide care that is ethical and affirming of the patient's orientation and identity. Unethical and shaming mistreatment should be regarded as medical malpractice.
