It wasn't until the publication today that we discover that Mr. Finch was a racist. We also find out that Scout herself has her own deep issues with race, and that moving to the North and being liberal doesn't make her a better person with regard to race or anything else. If anything, we find that both books, together, are an indictment of simplistic thoughts and the idea that there are easy answers to social problems.
Go Set A Watchman isn't as good as To Kill A Mockingbird, but it makes the point that racial issues aren't simple, and that thinking you're somehow better doesn't make it so.
Pretty poor "propaganda", considering that it complicates the story, and does nothing to make it easier to explain or understand.
Good propaganda is easily digestible. Go Set A Watchman, written before Mockingbird complicates and changes the story to include moral ambiguity. Harper Lee already knew what happened to her characters when she wrote Mockingbird. What happens is too complicated to make any sort of useful propaganda for anything.
I’m not talking about Watchman, I’m talking about To Kill a Mockingbird—the book that liberals saturate school kids with.
The lengthy book review posted by Ventilator(?) nearby is dead-on accurate about To Kill a Mockingbird as one-sided propaganda.
