The same claims of homosexuality are made against J. Edgar Hoover. Claims made it should be noted after he was dead. The morals at that time were so strictly exclusive of sodomy that the slightest hint would have destroyed him. Hoover was so powerful and thus made so many enemies that if in fact he was a cross dresser and/or homosexual those very same enemies would have seized upon those "facts" and destroyed him. Even Presidents feared that man's data files.
You first claim that it would be easy to blow the cover on Hoover for perverse behavior. then you claim even presidents feared his files on them. Not a very persuasive argument to say he wasn't a pervert.
Understood. There is a lack of primary source material on the subject, especially in English. Surprisingly few Nazi era documents have been translated from German.
A very well researched book by German historian Lothar Machtan titled The Hidden Hitler and now available in English. The Hidden Hitler details the available evidence for Hitler's homosexual orientation as well as that of other Nazis. The book is very well researched and is a compelling read. Throughout the book, Machtan backs up what he writes with extensive references to source material.
