Skin colour is immutable and cannot be changed. Homosexuality is more akin to alcoholism or drug addiction and can most certainly be altered if one chooses to do so. A fact remains a fact whether you choose to ignore it or not.
LIVING PROOF HOMOSEXUALS CAN CHANGE
Excerpts from "Homosexuality and the Truth" by Sy Rogers & Alan Medinger:
"Whatever may be the possible unlearned assistance from constitutional sources, the child's psychosexual identity is not written, unlearned, in the genetic code, the hormonal system or the nervous system at birth." - John W. Money. Ph.D., Johns Hopkins School of Medicine Professor
"Homosexuality, the choice of a partner of the same sex for orgastic satisfaction, is not innate. There is no connection between sexual instinct and the choice of sexual object. Such an object choice is learned, acquired behaviour; there is no inevitable genetically inborn propensity toward the choice of a partner of either the same or opposite sex." - Dr. Charles W. Socarides, Albert Einstein College of Medicine in New York.
"The genetic theory of the homosexual has been generally discarded today. Despite the interest in possible hormone mechanisms in the origin of homosexuality, no serious scientist today suggests that a simple cause-effect relationship applies." - Masters and Johnson
"The homosexual's real enemy is his ignorance of the possibility that he can be helped."- Dr. Edmund Bergler, "Homosexuality: Disease or Way of Life?"
"The success rate in 81 gays desiring reorientation (after a six year follow-up), is 71.6% (p.402) - Masters and Johnson - "Homosexuality in Perspective"
"For those homosexuals who are unhappy with their life and find effective therapy, it is 'curable'." - "Overcoming Homosexuality" by Dr. Robert Kronemeyer
"I've heard of hundreds of other men who have went from a homosexual to a heterosexual adjustment on their own." - Dr. Lawrence J. Hatterer (“Changing Homosexuality in the Male” p.138)
"The major challenge in treating homosexuality from the point of view of the patient's resistance has, of course, been the misconception that the disorder is innate or inborn." - Dr. Charles Socarides (from “Homosexuality” in the American Handbook of Psychiatry)
"I have recently had occasion to review the result of psychotherapy with homosexuals, and been surprised by the findings. It is paradoxical that even though politically active homosexual groups deny the possibility of change, all studies from Schrenck-Notzing on have found positive effects, virtually regardless of the kind of treatment used…” - Dr. Reuben Fine, Director for the New York Centre for Psychoanalytic Training. (“Psychoanalytic Theory, Male and Female Homosexuality: Psychological Approaches“ pp 84-86)
