I'm reading a Cracked article about inventions used for evil and there's a bit about loudspeakers being used by Hitler.
They linked a video with Hitler making a speech and describe it thusly:-
Up to about 2:00 in, he's speaking in a normal voice, then he gets a little louder, and a little louder, the crowd going apeshit every time he raises his voice. Now fast forward to the 9:00 mark and listen to him screaming his little mustache off, yelling himself hoarse, the speakers rattling the sound off the walls, pummeling the ears of a sea of white faces.
So, I watched it. It's the first time I've really watched Hitler make a speech. Sure, I've seen the Downfall meme a bunch of times (but of course that's fake Hitler). And I've been in the room when footage of Hitler has been on the tv but usually, it's background while a voice over narrates a particular point about history.
What I took from this experience is that if he shaved his facial hair and combed his hair even slightly differently, I would never recognise him. He just looks like some guy, you know.
And I can't help but think of this as a metaphor for how my culture deals with people with opinions and the will to act like Hitler. If they don't have a toothbrush moustache and a side parting, we don't recognise them. If they don't put a swastika on their arm, we don't see them for what they are. Even though every internet argument proves Godwin's Law if it goes on long enough, it's just a side show. We're comfortable calling internet strangers nazis but we're not good at recognising that people in positions of authority who just look like regular guys are saying the things and enacting similar decisions.
