You know you really have to step back and see this in context of the time period as well as the people's perspective. First off the camps were often in isolated areas near forests, fenced in. As someone else stated, people were in the trains to these camps for hours & days, not often knowing where the hell they were heading. It wasn't like Amtrak with a window. They were cargo cars. They were met by soldiers with guns & sometimes dogs. The Nazis didn't hesitate to use them either.
The people coming off the trains didn't know they were going to their deaths....that information didn't come out until at least 3 or more years into the war. Even people in the surrounding towns weren't sure what was going on in those fenced in areas. There wasn't an abundance of intellectuals walking around telling people---those were some of the first rounded up and put to death. There was NO mass communication. Most people didn't even have telephones, that was for business. Some people did rise up and try to fight, not on initial arrival but when they came to understand the REAL situation. It had to be very carefully and secretly planned. Also it took and immense amount of mental energy (motivation) to rise up once inside the camps as people didn't have much physical energy from starvation, and being beaten down every day, all day.
Propaganda can be skillfully used, but I'm not sure in what way do you mean.
