“everyone has something good about that, you have to find the redeeming quality and love the person for that.” what does this mean

  Everybody has their faults, and wasting time on all the bad qualities a person may have, focus on the good qualities, because instead of hating them, you may start to like them.

Explanation:

Even when Dinitia Hewitt beats Jeanette up with her friends, does Jeanette ever say a hateful word about her in this book.  Dinitia hated Jeanette because she thought Jeanette acted as if she were better than anyone else, but when she saw Jeanette bring her neighbor home she saw a different quality in Jeanette that she liked. So their relationship can relate to this quote because despite all the bad things the children say about Jeanette, Dinitia found a good quality to focus on.

the most appropriate strategy would be to do a questions and answer type speech.
