I have. Full recordings of his speeches are extremely rare and what most people see is the last few minutes where he's ranting and foaming at the mouth, and they wonder, how could anyone follow someone like this?
It's a show, an opera to be precise, and it's carefully choreographed and rehearsed. The audience is seeded with people who have already practiced going crazy at key moments, taking the crowd along with them. Every gesture, every pause, was rehearsed by Hitler before a mirror, usually in the upstairs of a flat next to the opera house belonging to his principal publicity photographer Hoffman. (Whose daughter, incidentally, was a confidante of Eva Braun and ended up marrying Baldur von Schirach).
Typically Hitler starts off quite restrained, even affable. The entire thing is a crescendo of resentment, self-righteousness, and hostility, peaking in those now famous rantings that have come to represent a madman in a frenzy (which he was). Not one bit of it was spontaneous.
When Hitler was spontaneous in private conversation during those now-notorious dinners where the unfortunate guests were forced to endure literally hours of self-indulgent blather, he was a much different and far less impressive figure.
He stopped appearing in public as the war proceeded to the disadvantage of the Nazis, relying on recorded radio speeches, the last of which was in January 1945, three months before the fall of Berlin. Pictures of him at that period show a palsied, broken man who looks twenty years older than the 56 he actually was. He was absolutely fine with Germany going down in flames as it had proven, in his estimation, unworthy of him.
That's what I know. Hope it helps a little.
Hitler understood theater, and especially opera, as a tool of politics. He once said, "You cannot understand National Socialism unless you understand Wagner." Having DVDs of Wagner's operas has let me understand his point.
LOL...sounds so like Mark Levin, except he actually upsets himself - but unlike Adolf he's anti-hate, sane and sincere. I'm kind of concerned he's going to stroke out one of these days.
