There's nothing unfortunate about acknowledging the racial themes in To Kill A Mockingbird, and doing so doesn't diminish any of the other messages. It would be a shit book if it were only about one thing. One of the things it's about is race, unpleasant as it may be.
That's correct, but the GP comment is unfortunate in that it is either a deliberate misinterpretation of my comment, or one made from a very superficial understanding of the text.
