Compare and contrast Helena Wolińska-Brus with Maria Gurowska.
They were both Jewish, Harry.
contrast Wolińska-Brus with any of the other participants in the Fieldorf murder who currently live in Poland (i.e. the ones who aren't Jewish).
All eight involved in Fieldorf's trial were Jewish as well.
Also compare and contrast Salomon Morel and Czesław Gęborski.
You finally found one Pole out of a dozen.
Don't get me wrong, I'm not favoring the Poles in this case. All were guilty of what we term 'court murder.' After living so many years here, you should have some understanding why no one has ever been convicted. I'd like to hear your opinion on that.
As to the Jewish/Jew nuance, Jews themselves would not agree with you, except when they try to distance themselves from crimes committed. How can they be victims and oppressors.
Let a Jew, or if you like, a Jewish person explain it to you:
The Jews active in official communist terror apparatuses (In the Soviet Union and abroad) and who at times led them, did not do this, obviously, as Jews, but rather, as Stalinists, communists, and "Soviet people." Therefore, we find it easy to ignore their origin and "play dumb": What do we have to do with them? But let's not forget them. My own view is different. I find it unacceptable that a person will be considered a member of the Jewish people when he does great things, but not considered part of our people when he does amazingly despicable things.
Even if we deny it, we cannot escape the Jewishness of "our hangmen," who served the Red Terror with loyalty and dedication from its establishment. After all, others will always remind us of their origin.
Instead, why don't you find the film with English subtitles so everyone can watch it.
