Can you give me some quotes on the issue of racism in Harper Lee's To Kill a Mockingbird?

    "It
couldn't be worse, Jack. The only thing we've got is a black man's word against the Ewells'. The
evidence boils down to you-did--I-didn't. The jury couldn't possibly be expected to take Tom
Robinson's word against the Ewells'--are you acquainted with the Ewells?" (88)

    Lula stopped, but she said, "You ain't got no business bringin' white chillun
here--they got their church, we got our'n. It is our church, ain't it, Miss Cal?" (119).  
This is a good example to show that there was a degree of racism on both sides of the color
line.

    "Well, Mr. Finch didn't act that way to Mayella and old man
Ewell when he cross-examined them. The way that man called him 'boy' all the time an' sneered at
him, an' looked around at the jury every time he answered--"

    
"Well, Dill, after all he's just a Negro." (199)
