What's some theme statement for chapter 20

I think there is the theme of people not appearing as they seem or stereotypes.Mr. Dolphus Raymond is known as the town drunk. Dill takes a sip and discovers Mr. Raymond is hiding a bottle of Coca-Cola in his infamous paper bag. Scout asks why he does such a thing, and Mr. Raymond explains he feels he has to give the population some reason for his odd behavior (being friendly toward black people). Mr. Raymond believes it's easier for people to handle strangeness when they have a reason to explain it. Thus, he pretends to be a drunkard. The same breaking down of stereotypes can be seen in the trial with Tom Robinson being tried as a criminal instead of a victim.
