And yes, the movie takes artistic liberties to take the viewer on this ride and tell it in the length of a movie.
Most nazis don't experience violence by PoC. They like this "defender" view, but in reality aren't under attack.
And this "the violence gets back to you" is a nice story. In reality, the nazis don't have to worry about revenge attacks. (To me, this stands out more than the location of the revenge attack.)
