I think you are approaching this from a position of afterwisdom. Case in point: Think how hard it was for the general american to realize the police in their country actually has pathological violent tendencies and blacks actually are in a weak position. If modern state is able to treat their minorities in that way in our enlightened age for a long time, think about what the chances the public had in WW2 Germany to have a clue. Generally, Germans trusted their government. The Nazi propaganda was astoundingly enticing (there were excellent books on WW1 propaganda that the Nazi:s studied from in earnest so they learned from existing knowledge). How good was the Nazi propaganda? People are still today falling in love with the concept, even though the Nazi idealism was proven evil and non-functional, and fascism itself inserted to modern day would be extremely anachronistic. Think about it. People are falling in love with a brand and ideology created by people who died 70+ years ago. Now imagine these same people are running a country. Portraying themselves as glorious leaders, and saying to all germans - hell yes, we will triumph, love us. And love they did. They have total pulse on the public sentiment. They control the mass media (they have mass media! Which is itself a novelty!). They control the public image of the state and they control the public mindset. They control the public news and what people are concerned off. I presume the public sentiment was along the lines of "So, they are moving those jews somewhere? Oh, better in some 'jewtown' rather than here in that ghetto, I'm glad I don't have to see them again". But I doubt they had in mind the slaughterhouse. It was horror what happened. But it is very hard to convince me the average german would have had any clue.
