I believe that all "deviant" or "unusual" self-identity issues like sexual identity, religious devotion, racial identity and extreme political dissidence, criminal activity, all "anti-social" self-imaging is probably reversible by some means. I also believe that psychotherapy cannot resolve these issues, since they occur at so basic a level that the patient is unable to achieve full candor wtih the therapist, or, maintian that level of candor with the general public. And its the interaction with the public that "reinforces" that self-image. I'm talking about any behavior where the indivdiual assumes his "manners" require him to conceal his "true self".
I also think 21st century science forbids exploration of therapy outside counseling to deal with these issues. The community and the government aren't going to allow experiments with drugs that allow devout Jews to be converted into Mormonism by talk, or surgery to make extreme reactionaries like me more persuasible.
Whether that is really a bad thing, depends on whether or not you are a real man. haha just kidding. at least it'd polite to say so.
