Still, they had Jewish background and as such they are eligible to be discussed in this thread.
I don't deny it. Nevertheless their culture is Polish, if not European.
On the other hand, Singer, originally from Lublin, is of Jewish culture. Szulc, from Drohobycz, talks about Jewish traditions and not badly with the tone of mockery (his many drawings of erotic excesses, even of the Orthodox)
What does it mean to you, your distinction "Polish Jews or Jewish Poles
I often provide such double distinction so that nobody feels hurt which sometimes happens when only one notion is offered and they feel excluded.
However, all of them had Polish nationality. It is not the fault of non-Jewish Poles, that 85% did not even speak the language and separated themselves from the others. In another European country, it would be unthinkable.
PS. I'm surprised you don't insult me, as you usually do. You owe me an apology. If I or someone else insulted your family without knowing them, like you did, I can imagine your violent reaction.
