The term "Homocaust" derived from "Holocaust" refers to the claims made by LGBT extremists that thousands or millions of homosexuals were exterminated by the Nazis in Germany under Adolf Hitler. This theory is false, it originated among activists who are not historians, and has been conclusively refuted by academic historians. Nevertheless, it continues to proliferate in the popular and liberal (leftwing) media, supported by a range of unsound evidence, and defended by the vigorous abuse of any who dare to disagree.
The claims were first put forward by Rüdiger Lautmann (born 1935), a German homosexual/pedophile activist. Lautmann is not a historian, merely a lecturer in sociology at the University of Bremen, who argues that pedophilia is harmless. He founded Selbsthilfegruppe Paedophilie, and has gone all over Europe making speeches on this topic. Lautmann alleged that the Nazis had rounded up a million homosexuals and sent them to be exterminated in concentration camps.
Proliferation to the UK
His claims were taken up by the British homosexual/pedophile campaigner Peter Tatchell who is also not a historian, and has no qualifications in research of any kind. He has a BA in sociology from a polytechnic. Tatchell used his website and newspaper articles to promulgate the myth and make it fashionable. In 2001, Tatchell denounced some of the leading historians of World War II because they did not subscribe to the Homocaust myth. He denounced Professor Sir Martin Gilbert (Fellow of Merton College, Oxford and acclaimed author of 88 books on WW2) and the late William Shirer (author of the classic The Rise and Fall of the Third Reich, who lived in Berlin during the war) because they take a different view. As evidence, Tatchell offered a film "Paragraph 175", about homosexual survivors of the Nazi era, which hardly supported the view that they had been exterminated. Many of those featured were in fact Jewish. In reply to Tatchell's claims, the expert historian Efraim Zuroff, of the Simon Wiesenthal Centre in Jerusalem, defended Sir Martin and said: "The word Holocaust refers to the specific Nazi intention to annihilate the Jews, and only the Jews. No other group of people was singled out in this way to be systematically wiped out..."
Spread on internet
Nevertheless, LGBT activists found the myth useful because it enabled them to portray homosexuals as victims. The names of various Jewish homosexuals who had been sent to concentration camps were placed on the website of the United States Holocaust Memorial Museum and similar sites of a popular, emotive nature to give a misleading impression that the inmates were there because they were homosexual rather than because they were Jewish.
These fallacies are exaggerated and sensationalized still further on the Homocaust website produced by British LGBT campaigners who are not historians. They encourage the belief that lesbians were sent to gas chambers, when the fact is that lesbianism has never been illegal at any time in German history and the only examples they can quote are Jewish women such as Henny Schermann, who was gassed at Ravensbruck concentration camp in 1942, because she was a Jew. The Homocaust theory is promulgated uncritically by such unreliable sources as Wikipedia and http://www.historylearningsite.co.uk/nazi-germany/homosexuals-and-nazi-germany/ These articles are not the work of professional historians. The websites offer blatant falsehood.
Several books by professional historians have challenged the myth. One is The Third Reich at War by Richard J. Evans, which gives a balanced view, revealing that most of the Nazis’ rhetoric against homosexuals was just that - rhetoric – and while a small number of male homosexuals were given prison sentences, Himmler frequently commuted them so that they could be sent into the army instead. The Routledge History of the Holocaust by Jonathan C. Friedman, reveals that although the death penalty applied to homosexual behavior among German army and SS officers, it did not apply to anyone else, and even in the SS it was rarely carried out. “Often the SS chief would relent and commute the sentence, if he could persuade himself that the guilty man was not a real homosexual, but had suffered a momentary lapse, especially under the influence of alcohol.” 
Myth refuted conclusively
The most thorough investigation of the Homocaust myth is Gunter Grau and Claudia Shoppmann’s Hidden Holocaust? Gay and Lesbian Persecution in Germany 1933-45. Written in German, by two historians of Humboldt University Berlin, it has been translated and published in English.  This book examines first-hand documentary evidence and reveals that during the entire Nazi period, the number of people convicted under anti-homosexuality laws was only 5,000 and they were sent to prisons or labor camps, not extermination camps. Half of that 5,000 survived the war. None were deliberately killed, but some died towards the end of the war of harsh conditions, such as cold, starvation and disease. No lesbians were arrested or jailed. So while the LGBT sites talk hysterically about 100,000 or a million victims, professional historians give a figure of 2,500 accidental deaths.
Misrepresentation tactics and methods
The bizarre publication history of this book gives some insight into the mentality of the people who spread the Homocaust myth. Although Grau and Shoppmann’s book conclusively refutes the claims that the Nazis carried out any large-scale killing of homosexuals, the blurb of the book on the Routledge website says the opposite. It claims the book upholds LGBT activists’ version of history. The fact that they will go so far as to misrepresent an academic book in order to uphold their false world-view could provide useful evidence for a debate on whether homosexuality is a form of insanity. This misleading blurb is reproduced on Google books and elsewhere, perpetuating the fallacy and giving it bogus academic respectability.
LGBT websites widely use photo-shopped pictures to uphold the Homocaust myth. A famous photograph of men in Buchenwald concentration camp is in the US Holocaust Memorial Museum, and is provisionally dated 1939-41. Pale gray triangles are faintly visible on some of them, and could have had a number of meanings as triangles of six different colors were used. The picture is reproduced widely with fake pink triangles added to it, on such LGBT websites as http://www.stop-homophobia.com/thegayholocaust.htm and https://libcom.org/tags/world-war-2 Presumably, the LGBT activists have copied it from the website of the museum, and doctored it to their own requirements.
Uses of the myth
The Homocaust myth, which originated with pro-pedophile campaigners, continues to be used by them to advocate their views.

Until recently the discussion has remained speculative: most of the relevant documents were stored in closed East German archives, and access was denied to scholars and researchers. As a result of the unification of East and West Germany, these archives are now open. Hidden Holocaust, by the German scholars Gunter Grau and Claudia Shoppmann of Humboldt University, Berlin, demonstrates that the eradication of homosexuals was a declared goal of the Nazis even before they took power in 1933, and provide proof of the systematic anti-gay campaigns, the methods used to justify discrimination, and the incarceration mutilation and murder of gay men and women in Nazi concentration camps. A chilling but ground-breaking work in gay and lesbian studies."
