Josef Meisinger, a Gestapo colonel who becomes known as the Butcher of Warsaw, gives a speech explaining why it's necessary to arrest homosexuals and prosecute them as enemies of the state. One of Meisinger's primary jobs in the Gestapo at this time is Bekämpfung der Homosexualität und der Abtreibung ("Campaign against Homosexuality and Abortion").
Josef Meisinger explains:
"Since, as we know, homosexuals are useless for normal sexual intercourse, homosexuality also has an effect on young blood and will eventually lead to a drop in the birth rate. The result is a general weakening of the nation's strength of the kind that threatens not least a nation's military capacity.
In the end, however, homosexuality is a permanent threat to order in the life of the state. Apart from being itself a punishable violation of that order, it is especially dangerous because it is often the starting point for a series of further crimes. Very often it comes as a preliminary to treason and, in numerous cases it lays the basis for blackmail. ...
If one is really to appreciate the hidden danger of homosexuality, it is no longer enough to consider it as before from a narrowly criminal viewpoint. Because it is now so enormously widespread, it has actually developed into a phenomenon of the most far-reaching consequence for the survival of the nation and state. For this reason, however, homosexuality can no longer be regarded simply from the viewpoint of criminal investigation; it has become a problem with political importance. ...
I should mention here that experience has shown beyond doubt that only a vanishingly small number of homosexuals have a truly homosexual inclination, that most of them by far have been quite normally active at one time or another and then turned to this area simply because they were sated with life's pleasures or for various other reasons such as fear of venereal diseases.
I should also say that, with firm education and order, and regulated labor, a great number of homosexuals who have come to the attention of the authorities have been taught to become useful members of the national community."
