Check out “The Pink Swastika” - it’s all online. The Nazis didn’t kill homosexuals, many of them were homosexuals!

The fact of the rival paramilitary force, controlled by Ernst Roehm who was homosexual being assassinated, gave them some credence. Hitler's mob did him in. Of course it was a power struggle, Roehm would have been a gonner anyway. For those living just after WW2, they were inundated with the "information" that the homosexual, the gypsy and the mentally deficient were confined to the concentration camps. Thus anyone having doubts about the first two, could be compare to a "Nazi". Very clever move.
There was even an attempt by the British television network to claim many of the heroes of "The Battle of Britain" consisted of the elite "public schools" who became fighter pilots. A rebuttal appeared, this was too much to stomach, the rebuttal was titled "The Gaying of the Royal Airforce". A former Wing Commander said the records of the air aces, showed they were Flight Sgts, not the officer class which was automatically given officer status.
At that time the penalty for over homosexual acts was a maximum of seven years jail. Unlikely practice among lower class Flight Sgts. It was a cartoon character created during WW2 of an upper class officer, with his cries of "Tally Ho" and "Wizard Prang" who came from the elite classes. Seized on by the homosexual lobby, to assign homosexuality to the Royal Airforce.
Finally even politically correct televison had stepped over the line. Many of those Battle of Britain airmen were still living.
