Read William Shirer's seminal work "Rise and Fall of the Third Reich" - at least in the chapters involving the SA (commonly known as "brownshirts") who were indispensable for getting Hitler into power. Be forewarned though: Shirer wrote most of it in the 1950s, and frequently uses the word "perversion," a commonly understood word back then, but one which can grate on tender ears born after the 50's that have only heard euphemisms like "alternate lifestyle".
You can also google "Ernst Rohm", the SA leader and #2 or #3 Nazi, until Hitler executed him and the rest of the SA leadership (a preponderance of whom were homosexuals) in a Machiavellian bargain with the German Army leadership, soon after the SA had vaulted him into power and he no longer needed them, but at the time desperately needed the loyalty of the Army.
Of course, anything from Wiki or other mainstream or liberal web sources is going to have the SA's sexual proclivities heavily played down. Better to buy a book on the subject - eg The Pink Swastika
I have the Rise and Fall of the Third Reich and never saw an allusion to homosexuality. However, that could be because my mind wasn’t aware of the depravity, at the time I read it. I will recheck.
Homosexuals a.k.a. as the depraved, started using WWII as a backdrop in the 80’s as a means to establish that they were ‘persecuted’ in the same way as the Jewish people, which is ludicrous. By injecting this premise, people would jump to the conclusion that it is indeed, a ‘civil rights’ issue. In other words the homosexuals try to equalize the treatment of the jews to their position which is completely contrary to logic or reasoning imo. If this ‘group’ was truly targeted like the jews and other groups, it would have been duly noted in written history. I’m not buying that they were targeted like other groups.
