I agree that curiosity plays a big role.

How do you like it?

It's another look into Hitler's mind and how his hate of Jews got escalated. Another perspective I'd say.

Hitler was a white nationalist? He thought Slavs were sub-humans, and they are quite white.

When times are bad, people like to find others to blame. Like Hitler, Trump uses fear and hate to manipulate the uneducated and ill-informed, and he has succeeded.

@Cierzo: I guess in Hitlers eyes Slavs weren't white enough. It's a recurring theme in history. Blame those other people for all of your problems and all will feel better...

@HairyBallSack1: True. This is probably the intentions of news like these.
I bet many of those who bought and read it had this thought in mind 'let's see if this guy is the absolute devil that media have portraited'. And I bet too that such a thought was in the origin of the soaring sales of The Communist Manifesto when the financial crisis broke out.
