Go Set a Watchman

So Scout finds out that her dad Atticus is a racist, and she's not because she's “color blind” (but would never marry a black person so is she really) and then in the end she forgives him and all is well.

Feels bizarre to me because the climax of the book is Scout's argument with Atticus, and the resolution is that she was wrong to argue because Atticus is a racist but at least he's not a mega-racist?

Feel like the book should have come with an introduction explaining that it's just a draft of a book, it feels wrong that it's been sold as-is.
