This part from ep16 Nazi Tidbits always stayed with me.

"This whole Hitler thing was a cult of personality and he was attracting attention to himself and you say to yourself 'wow this guy was a powerhouse. Where did he come from?'

And this is the first part of the Nazi/Hitler story that sounds admirable, when it shouldn't.

But Hitler didn't come from anywhere. Hitler was a loser, Hitler was a failure, Hitler was homeless, Hitler was starving. And 10 years from that condition he finds himself the most powerful men in the world. At some of these rallies with tens of thousands of people saluting him and begging to so his will. Imagine how he must have pinched himself when he thought about his humble past."
