The homosexual cabal, led by Judson Marmor and Robert Spitzer, among others, rolled the American Psychiatric Association, keepers of the Diagnostic and Statistical Manual, in 1972. There was a professional debate with people who knew what they were talking about, but the debate (about taking homosexuality out of the DSM) was actually carried by cabalistic politicking. It was literally a conspiracy against the truth, and against their colleagues.
Judson and Marmor got the second APA, the American Psychological Assn'., to establish Division 44, to be a Gay Gestapo over political and "scientific" correctness on all discussions and professional work on e.g. the etiology of homosexuality -- but it had been removed from the DSM list of paraphilias kept by the other APA, so no paper on homosexuality as a disorder will any longer appear under the aegis of either APA; in fact, some people have lost their professional credentials. (Gay Nazis always go after people's profession, job, or bank balance.)
Division 44 rules, like Hitler's SS-Ahnenerben, over all questions of origins and truth. The Official Truth is known. Dissent at your peril.
