National professional organizations like American Psychology Association, American Psychiatric Association, American Counseling Association, American Social Workers Assocation, etc. have all found that conversion therapy (CT) is not consistent with sound and ethical practices for licensed practicioners. At the very least, using CT for the purpose of attempting to change an individual's sexual orientation or gender identity or expression is unethical, as it has never been shown as effective in any well-respected peer-reviewed research, and at worst, is likely to be harmful. Enacting guidance 125-9 is not a matter of free speech, as speech that has been demonstrated to do harm is not protected under the US Constitution.
