One great example comes from Atticus, in regards to Mrs. Dubose. Mrs. Dubose calls Atticus filthy names, and hates many of his views about equality and fairness. Her tongue is acidic and merciless, as Jem finds out walking past her house into town in chapter 11. Despite her nasty nature, and the personal insults that she constantly dishes out to him, Atticus demonstrates great tolerance towards her. Not only is he kind to her in return, by sending Jem to help her out in her final moments of life, but he looks beyond her bitter and insulting ways, trying to see her for her positive traits. As he tells Jem at the end of chapter 11, Atticus is able to see that Mrs. Dubose is "a great lady" who was "the bravest person I ever knew." If that isn't a tolerant viewpoint of a lady who was insulting and awful, then I don't know what is.
I hope that helps to get you started; good luck!
Atticus also shows great tolerance toward the Cunningham clan of Old Sarum in To Kill a Mockingbird. The Cunninghams are by all rights honest, hard-working (though unlucky) people. Atticus was willing to accept payment of goods for his legal services, and Walter Cunningham eventually paid him off after Atticus represented him. However, Cunningham was one of the men who threatened to harm Atticus when he defended Tom Robinson from a lynching at the jail. Atticus later points out that it was one of these Old Sarum men who served on the jury and was the initial holdout before finally giving in and voting for Tom's guilt.
I think that one example of tolerance in the book is when Jem and Scout go to church with Calpurnia. The first lady they meet is intolerant -- she doesn't want any white people at the black church. But the rest of the church is much more tolerant. I would use that one.
I think you could also say that Atticus is tolerant when he allows Mr. Cunningham to pay him with stuff rather than money. In a way, that's being charitable rather than tolerant, but you can also say that he is tolerating different kinds of people rather than forcing them to be like him.
Another one can be seen where Atticus is nice to Mrs. DuBose even though she is really nasty to him and to his kids.
one other thing. with these examples how do they or what effects do they have on Scoutt and Jem. I need examples or both of them.
these are all great answers cheers peeps
