She tells Nina, "Impudent girl!--brazen-faced, impudent, bad girl! Do you not know that you would bring disgrace upon us all ?" To Nina's father she says, "Tell me that at once, Josef, that I may know.

Has she your sanction for--for--for this accursed abomination ?" To her husband she says, "Oh, I hate them! I do hate them! Anything is fair against a Jew." And during a meeting with Anton she exclaims, "How dares he come here to talk of his love?
It is filthy--it is worse than filthy--it is profane." Anton's family also opposes the marriage, but Anton's father's behavior toward Nina is in sharp contrast to that of her aunt: The old man's heart was softened towards her.

He could not bring himself to say a word to her of direct encouragement, but he kissed her before she went, telling her that she was a good girl, and bidding her have no care as to the house in the Kleinseite.

As long as he lived, and her father, her father should not be disturbed.
Anton, being more a businessman than a lover, at times behaves insensitively toward Nina.

Otherwise, throughout the novel, the Jewish characters act with honesty and kindness.
