I can't help but think one of the most appealing aspects of Hitler would've been his ability to deliver passionate speeches.
For example, I have no idea what he's saying in this speech [1], but the tone at which he delivers it is undeniably quite mesmerising, especially when compared to the tone of, say, Joe Biden [2].
In a time where radio ruled, it's hard not to think he wouldn't stand out, irregardless of the content contained in his speeches.
