The questions about race are raised very often in the book.
From the one side the children, who are still innocent and unaware about such prejudices ask outright armor-piercing questions.
“To kill a Mockingbird” is a great educational book that is written in easy language and shows lots of very important problems of prejudices and self-identification through the kid’s eyes.
One of the major and most common problem of that time is, surely, racism.
Jem bitterly admits that even going as far in time as to the Old Testament and finding a drop of black blood may cause this.
He adds that recently he thought that it didn’t matter.
Great that it was only one black woman who treats them like this for entering the church for black people.
The local garbage collector apologizes for her – not because Jem and Scout are white, but just out of good attitude to the kids.
The woman talking about them like that behaves like the kids aren’t even present, or they are inanimate objects – in a way that masters treated their black slaves before.
This encounter absolutely convinces them that racism has nothing to do with laws or even something relatively right.
