What do we learn about Mr. Raymond? Do you agree with his decision to deceive people?

Scout asks why he does such a thing, and Mr. Raymond explains he feels he has to give the population some reason for his odd behavior (being friendly toward black people). Mr. Raymond believes it's easier for people to handle strangeness when they have a reason to explain it. Thus, he pretends to be a drunkard. He says he thinks that children like Dill, who is so upset over the trial, haven't lost the instinct that tells them that it's wrong for white people to "give hell" to black people without consideration for their basic humanity.

I don't know if I agree with his deception, but I do understand it. There are certain things that just don't concern other people and shouldn't have to be explained. People should mind their own business.
