I personally find the book Adventures of Huckleberry Finn to be a anti-racist book. That is my opinion for these reasons, it was one of the first books of it's day to show a black man as a true person. Secondly it showed the truth of how cruel southern society was. And last, the realism the book tried to show throughout the story. The Adventures of Huckleberry Finn was one of the first books of it's day show a black man as a true person. There are many examples of this throughout the book, such as when Jim discusses his family and how he wants to go be with them.
Jim also shows feeling, for example when Huck and Jim get split up on the rafts Jim worries about Huck, and is concerned for him. Jim also show honesty and dedication, an example is towards the end of the book when Jim sacrifices his freedom to help Tom and the doctor after Tom has been shot. So you see the book shows that black people are human beings that have emotions and feelings. The book also shows the true cruelty of southern society. There are many examples of this in the book.
Like the Sunday school discussing how setting blacks free was a deadly sin. And the constant negro sales throughout the book. And how black people had no respect and weren't looked upon as human beings. So what Mark Twain is trying to tell the reader is how cruel the south was to blacks and how ridiculous the southern society was. I think the book also tries to show realism of what the south was like during it's slave years. Many people think that when Mark Twain uses the word he is being racist.
But really Twain is trying to bring realism and reality to the book. Also the use of slang within the book is used for the same thing. So Twain is letting the reader know what it would have been like to live back then and how corrupted the south had become. So for these reasons I believe that the book Adventures of Huckleberry Finn is not racist and is clearly sticking up for black people and there rights.
