"Panelists Recount Events Leading to Deleting Homosexuality As a Psychiatric Disorder From DSM:
"Twenty-five years ago APA leaders, in the glare of a national media spotlight, took the controversial step of deleting homosexuality from the Association's compendium of psychiatric disorders. That action launched APA on a quarter century of efforts to end discrimination against homosexuals and coincided with the increasing willingness of gay and lesbian psychiatrists to insist openly that APA must listen to them."
Interesting article. You can see how the gay community played a significant role in having this changed.
It would be akin to the schizophrenic community getting schizophrenia removed from the APA manual. French homosexual philospher Michel Focault argued schizophrenics were simply misunderstood and not sick.
Any honest scientist would examine the "studies" the APA cited to remove homosexuality from the DSM and see they were so riddled full of errors as to be invalid.
