@Walter Hinteler,
"... gay men were one of the first groups targeted by the Nazis..."
True, but that only demonstrates the cynical hypocrisy of the Nazis.
"There's no historical evidence that the SA had been infiltrated by homosexuals..."
There's plenty. See for example Chapter 7 of The Rise and Fall of the Third Reich by William L. Shirer.
Karl Ernst, leader of the Berlin S.A. (ex-bouncer at a cafe frequented by homosexuals); S.A. Obergruppenfuehrer Edmund Heines, a "notorious homosexual" who was actually found in bed with a young man when Hitler and his raiding party stormed the Hanslbauer Hotel where Roehm and his S.A. lieutenants were sleeping.
The tales of "the corruption and debauchery of the homosexual clique surrounding the S.A. chief" were widely circulated. Field Marshal von Brauchitsch, Army Commander in Chief, stated in recorded testimony given after the war, that "rearmament was too serious and difficult a business to permit the participation of peculators, drunkards and homosexuals".
There is also evidence that Hitler knew about and was fairly indifferent to homosexuality among the S.A. leadership until it suited his purposes to suppress the organization.
"...the 'Sturmabteilung' was no "leadership" of a "political movement" but the paramilitary wing of a political party, the NSDAP."
The S.A. was also the political vanguard of the party. "It was Roehm, chief of the S.A., who coined the phrase "the second revolution" and insisted that it be carried through. He was joined by Goebbels..." And of course, the S.A. formed the core of Hitler's mass political movement. Roehm was named the deputy leader of the party, along with Rudolf Hess, on December 1, 1933.
" Tangential as well, but in my opinion not funny at all..."
I found Ciano's characterization of Goering most amusing. But then, I am not an admirer of Goering or the Third Reich.
