historical story (antisemitism, politics))
Ever hear of the Judenzaehlung or Jew Census? It's part of the ramp up to what happened in the 30s/40s.
In 1916 Germany's high command (OHL) decides to tally where Jews are in their military. They assume HORRIBLE OUTSIDERS SHIRKING/IN GREEDY QUARTERMASTER POSITIONS etc.
The census promptly finds most Jews are in front-line combatant positions instead. So OHL promptly sits on the data and lets Germans reach whatever anti-semitic conclusion they like.
