What are some examples of racism in the story To Kill a Mockingbird?

In , Lee
reveals the predominant prejudice throughout the town by illustrating Cecil Jacobs's comments
about Atticus. Cecil announces on the playground that "s daddy defended niggers" (Lee,
77).

In ,and Scout walk past Mrs. Dubose's home when she begins to make
derogatory, racist comments about Atticus. Mrs. Dubose reveals her racist personality by telling
Jem,

Your fathers no better than the niggers and trash he
works for! (Lee, 105).

In , the Old Sarum bunch arrives
at the Maycomb jailhouse the night before the trial and attempts to lynch Tom Robinson. Their
actions reveal their racist ideology. Fortunately, Atticus prevents the mob from lynching Tom
Robinson.

In , Jem and the children are sitting outside of the courthouse
discussing the backgrounds of various citizens when Jem mentions that Dolphus Raymond has mixed
children. Jem goes on to comment that mixed children are "real sad." He tells
Scout:

They dont belong anywhere. Colored folks wont have
€˜em because theyre half white; white folks wont have em cause theyre colored, so theyre just
in-betweens, dont belong anywhere (Lee, 163).

Following
Tom's unfortunate death, Scout reiterates the town's racist reaction by saying,

To Maycomb, Toms death was typical. Typical of a nigger to cut and
run. Typical of a niggers mentality to have no plan, no thought for the future, just run blind
first chance he saw. Funny thing,mightve got him off scot free, but wait? Hell no. You know how
they are. Easy come, easy go. Just shows you, that Robinson boy was legally married, they say he
kept himself clean, went to church and all that, but when it comes down to the line the veneers
mighty thin. Nigger always comes out in €˜em (Lee, 244).

In , Scout recognizes her teacher's hypocrisy when she mentions that people in America
do not believe in persecuting anybody. However, Scout recalls overhearing Miss Gates make a
racist comment while leaving the courthouse. Scout tells Jem:

I heard her [Miss Gates] say its time somebody taught em a lesson, they were gettin€˜
way above themselves, an the next thing they think they can do is marry us (Lee, 251).
