What does Mrs.Dubose say about the children's mother? How does Jem feel about this ?chapter 11 of To Kill a Mockingbird

She insults the Finches. On page 102 as Jem and Scout are walking home, Mrs. Dubose begins hurling commentary at them. Lee observes, " . . . we were followed up the sidewalk by a philippic on our family's moral degeneration, the major premise of which was that half the Finches were in the asylum anyway, but if our mother were living we would not have to come to such a state" (102). This is just too much for Jem, who has already put up with Mrs. Dubose telling him that his father is no better than the black people he defends. When Mrs. Dubose implies that Atticus is doing a poor job as a parent and that his mother would never let him defend Tom Robinson, Jem loses it.
