Why Does Scout Have Such Poor Follow Through?

In the ending of Go Set A Watchman, scout confronts her father and henry about being members of basically, the smaller and more secretive version of the KKK. She basically gives them the burns of the century, is about to go back to NY, but somehow her uncle hitting her in the face and spewing a bunch of racist-apologetic things make her think that she is the one on the wrong and needs to apologize. 

If I were to try and pull a quote this blog post would be about ten pages long, so I'll just tell you why her backing down and not following through with what she believes in is wrong. 

She shouldn't forgive Atticus and henry, because they go against the moral code that they preach to everyone, and because Atticus Finch believes black people to be a "backwards group of people, and still in their child hood stage as a race" I am not kidding, your dear beloved Atticus finch says this in the book. 

Another much less but still aggravating remark Atticus makes is when he offhandedly says "Now that I've adjusted my ear to feminine reasoning, I think we can find ourselves believing in the very same things" (lee, 243)

This is another quote that shows how sexist Atticus is. Does he imply that "feminine reasoning" is idiotic, or somehow lesser? I believe he is trying to make scout feel like a child. one of the many things that the patriarchy is guilty for. 

Monroe Freedman, you were right. This time...
