How does Harper Lee satirise the white community in this chapter?

Harper Lee satirises the white community by juxtaposing the black and white communities’ reactions. The black community reacted to Atticus’ actions in helping Tom Robinson and standing for what is right by giving him food and showering him with gifts and Atticus’ reaction reflects the type d person he is, he says ” I’m very grateful but tell them they must never do this again, times are too hard” he is a very humble man that knows what is good and what is bad. The White community however react in a very negative way, by gossiping about why Jem and Scout were in the “coloured balcony”, you can see the contast in the attitude the white and black community have towards each other.
After the trial, Jem and Scout both cry after Tom Robinson was fiund guilty, they cried because the truth was so obvious and present yet the White community still chose to convict Tom Robinson of a crime he had not committed and they cried because the people were so blind and didn’t see their mistakes.
When Jem and Scout are seen by Miss Maudie, she offers them a slice of cake and without saying anything she showed to the Finch Family that nothing had changed after the trial and the case, and she shows her kindness with this small act and Harper Lee shows that not all of the White community was the same, and that Articus wasn’t the only mockingbird.
