In Harper Lee's book, To Kill A Mockingbird, there are many examples of racism. During this time in history racism was acceptable. Racism is a key theme in her book.
Not only those who were black, but also those who affiliated with blacks, were considered inferior. Atticus, a lawyer, who defended blacks in court, was mocked. An example of this is when Mrs. Dubose said, "Your father's [Atticus] no better than the niggers and trash he works for!” Mr. Dolphus Raymond was also criticized for affiliating with blacks, especially black females. Example is when Jem said, "He likes 'em [blacks] better 'n he likes us [whites], I reckon.” Basically, you were black if you "liked” blacks.
Blacks, because they were considered inferior, were expected to do everything for whites. Everything had to be perfect, without excuse. Even when Calpurnia, a Finch family friend, did not make the perfect cup of coffee, she was mocked. Book excerpt, "She [Calpurnia] poured one tablespoon of coffee into it and filled the cup to the brim with milk. I [Scout] thanked her by sticking out my tongue...”. Even when blacks did do good, they were still mocked. An example is when Aunt Alexandra said, "Jem's growing up now and you are too. We decided that it would be best for you to have some feminine influence.” Even though Calpurnia was a female, Aunt Alexandra over-looked this, because of her race. People were so biased, it didn't matter how good a job a black person did.
Since there was such strong racism in Maycomb, there were excuses made for whites. In the book, it was obvious that Bob Ewell was a mean man. It was also obvious that he was abusive to his daughter, Mayella, and he was the one who violated her, not Tom Robinson, because what the evidence showed. But, the people of Maycomb over-looked the evidence in favor of Tom Robinson, just because he was black.
