Tim Johnson is an example of Racism in to kill a mockingbird. Atticus tells Scout and Jem that it is a sin to kill a mockingbird and then he kills the rabid dog.
Come help me in my house! I'll give you a nickel. All my siblings are gone getting icecream
Radical discrimination was a very large theme in to kill a mockingbird. Tom Robinson is in the court room with Atticus.
I'll do my best to prove to them that you're innocent.
Tom Robinson (black man) is accused of raping a white woman named Mayella, and Atticus must overcome the prejudice and preconceptions people of Maycomb have against Tom Robinson.
Race does not define a person's inner character. Mayella is a young white girl in Maycomb. However, her physical appearance is deceiving of her true character- a desperate lair willing to hurt others because she's been hurt.
Tom Robinson is a mockingbird. He is kind & caring. He has no intentions of harming anyone. He is a mockingbird because he is innocent, but unfortunately is convicted and charged guilty mainly due to his race.
Boo Radley is a mockingbird. He has a reputation of being a psychopathic killer, but he is actually scared, kind man, and literally a life-saver. He appears when needed most to save Jem and Scout from being killed by Bob Ewell and proves to them and everyone that he is not the insane killer person they thought he was.
