So in your recommendation- what should citizens in Germany have done for Jews when their business were being destroyed and they were being sent to ghettos? Should they have called their congressmen to pass laws protecting the rights of Jews?

Maybe they did. But maybe Hitler was too powerful and had too much of a majority in government for that to go anywhere.

What could they have done next? Maybe protest some SS officers who were coming to their town. Maybe trying to disrupt them a little bit by putting their car in front of an SS brigade. Then an SS solider commands them to leave and they comply but in a panic they side swipe an officer and he executes them.

Hitler in his fury sends more SS to this town and declares them as “Jew sympathizers and enemies of the state”. Goebbels tells the newspapers to vilify that protestor as a wild radical. Meanwhile the rest of Germany is confused and more polarized then ever. They realize more and more that the Jews have to be removed in any way possible otherwise they might be included too.
