nor what the rest of the world did to us once World War 2 ended.

There's a reason jews and dissidents are the only holocaust victims publicly talked about. I am german, went to school in Germany (history lessons about the Third Reich, Holocaust and WW2 are super extensive here and take up basically 3-4 school years), yet we only ever talked about jews and dissidents of the nazis. No Sinti and Roma, no queers, no nobody else was ever talked about during these lessons.
