In Chapter 23 of Harper Lee's To Kill a Mockingbird we find Atticus Finch being victimized by Bob Ewell. Atticus has basically exposed Mr. Ewell for the lies he tells and the way of life with which he carries on in Maycomb. As a result, Ewell is mad and wishes to destroy Atticus Finch.
The specific incident of victimization and bullying occurs at the beginning of this chapter, when Ewell not only spits his tobacco at Atticus, but tempts him to fight by calling him names that people would not even repeat.
One of the questions Ewell asks is whether Atticus is too proud to fight him. To this, Atticus answers:
No, too old, [he then] put his hands in his pockets and strolled on.
We as readers can conclude that Atticus is not a man of war. He would not lower himself to the nonsensical and immature behavior of a man like Ewell. He, contrastingly, took the situation quite lightly and simply said about it:
I wish Bob Ewell wouldn't chew tobacco.
We also know that Atticus refuses to get a gun, and does not seem to be too afraid of the social wrath to which he has become exposed as a result of Tom Robinson's trial. In all, he is a gentleman's gentleman and an extremely courageous man who does not have to show his strength by the use of his hands, but by his appeal to common sense.
